Addendum

ADDENDUM

This addendum contains information that relates to the F35 Multiple Feeder Protection System, version 5.8x. This addendum lists a number of information items that appear in the instruction manual GEK-113550A (revision V2) but are not included in the current F35 operations.

The following functions and items are not yet available with the current version of the F35 relay:

•N/A.

Version 4.0x and higher releases of the F35 relay includes new hardware (CPU and CT/VT modules).

• The new CPU modules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S.

• The new CT/VT modules are specified with the following order codes: 8F, 8G, 8H, 8J 8L, 8M, 8N, 8R.

The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:

MODULE OLD NEW DESCRIPTION

CPU 9A 9E RS485 and RS485 (Modbus RTU, DNP)

9C 9G RS485 and 10Base-F (Ethernet, Modbus TCP/IP, DNP)

9D 9H RS485 and redundant 10Base-F (Ethernet, Modbus TCP/IP, DNP)

--- 9J RS485 and multi-mode ST 100Base-FX

--- 9K RS485 and multi-mode ST redundant 100Base-FX

--- 9L RS485 and single mode SC 100Base-FX

--- 9M RS485 and single mode SC redundant 100Base-FX

--- 9N RS485 and 10/100Base-T

--- 9P RS485 and single mode ST 100Base-FX

--- 9R RS485 and single mode ST redundant 100Base-FX

--- 9S RS485 and six-port managed Ethernet switch

CT/VT 8A 8F Standard 4CT/4VT

8B 8G Sensitive ground 4CT/4VT

8C 8H Standard 8CT

8D 8J Sensitive ground 8CT

-- 8L Standard 4CT/4VT with enhanced diagnostics

-- 8M Sensitive ground 4CT/4VT with enhanced diagnostics

-- 8N Standard 8CT with enhanced diagnostics

-- 8R Sensitive ground 8CT with enhanced diagnostics

The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S), and the old CT/VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mismatches, the new CPU and CT/VT modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and DSP module label colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module, the relay will not function and a

DSP ERROR or HARDWARE MISMATCH error will be displayed.

All other input/output modules are compatible with the new hardware.

With respect to the firmware, firmware versions 4.0x and higher are only compatible with the new CPU and CT/VT modules. Previous versions of the firmware (3.4x and earlier) are only compatible with the older CPU and CT/VT modules.

1 GETTING STARTED 1.2 UR OVERVIEW

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR

Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This first generation of equipment was gradually replaced by analog electronic equipment, most of which emulated the singlefunction approach of their electromechanical precursors. Both of these technologies required expensive cabling and auxiliary equipment to produce functioning systems.

Recently, digital electronic equipment has begun to provide protection, control, and metering functions. Initially, this equipment was either single function or had very limited multi-function capability, and did not significantly reduce the cabling and auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing cabling and auxiliaries significantly. These devices also transfer data to central control facilities and Human Machine Interfaces using electronic communications. The functions performed by these products have become so broad that many users now prefer the term IED (Intelligent Electronic Device).

It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further reduced, to 20% to 70% of the levels common in 1990, to achieve large cost reductions. This requires placing even more functions within the IEDs.

Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.

High speed communications are required to meet the data transfer rates required by modern automatic control and monitoring systems. In the near future, very high speed communications will be required to perform protection signaling with a performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3 milliseconds. This has been established by the IEC 61850 standard.

IEDs with the capabilities outlined above will also provide significantly more power system data than is presently available, enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control systems. This new generation of equipment must also be easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Universal Relay (UR) has been developed to meet these goals.

1.2.2 HARDWARE ARCHITECTURE

a) UR BASIC DESIGN

The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output signals. The UR can communicate over a local area network (LAN) with an operator interface, a programming device, or another UR device.

Figure 1–2: UR CONCEPT BLOCK DIAGRAM

The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as programmable logic gates, timers, and latches for control features.

Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into logic signals used by the relay.

Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used to control field devices.

b) UR SIGNAL TYPES

The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’ contacts are supported.

The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize the device. Virtual outputs can also serve as virtual inputs to FlexLogic™ equations.

The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec- tors (RTDs).

The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines. The UR-series relays support 1 A and 5 A CTs.

The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic™ operands inserted into IEC 61850 GSSE and GOOSE messages.

The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are connected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilotaided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.

c) UR SCAN OPERATION

The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the logic program (FlexLogic™ equation), and then sets each output to the appropriate state in an output status table. Any resulting task execution is priority interrupt-driven.

Figure 1–3: UR-SERIES SCAN OPERATION

1.2.3 SOFTWARE ARCHITECTURE

The firmware (software embedded in the relay) is designed in functional modules which can be installed in any relay as required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.

Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept, one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instantaneous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent completely self-contained software modules. The same object-class concept can be used for metering, input/output control, hmi, communications, or any functional entity in the system.

Employing OOD/OOP in the software architecture of the F35 achieves the same features as the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various functionality classes. This results in a common look and feel across the entire family of UR-series platform-based applications.

1.2.4 IMPORTANT CONCEPTS

As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understanding of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in “elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5. Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of chapter 5. An explanation of the use of inputs from CTs and VTs is in the Introduction to AC sources section in chapter 5. A description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic™ section in chapter 5.

Please refer to Chapter 3: Hardware for detailed mounting and wiring instructions. Review all WARNINGS and CAUTIONS carefully.

1.4.2 COMMUNICATIONS

The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ethernet ports. To communicate via the faceplate RS232 port, a standard straight-through serial cable is used. The DB-9 male end is connected to the relay and the DB-9 or DB-25 female end is connected to the PC COM1 or COM2 port as described in the CPU communications ports section of chapter 3.

Figure 1–7: RELAY COMMUNICATIONS OPTIONS

To communicate through the F35 rear RS485 port from a PC RS232 port, the GE Multilin RS232/RS485 converter box is required. This device (catalog number F485) connects to the computer using a “straight-through” serial cable. A shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the F35 rear communications port. The converter terminals (+, –, GND) are connected to the F35 communication module (+, –, COM) terminals. Refer to the CPU communica- tions ports section in chapter 3 for option details. The line should be terminated with an R-C network (that is, 120 Ω, 1 nF) as described in the chapter 3.

1.4.3 FACEPLATE DISPLAY

All messages are displayed on a 2 × 20 backlit liquid crystal display (LCD) to make them visible under poor lighting conditions. Messages are descriptive and should not require the aid of an instruction manual for deciphering. While the keypad and display are not actively being used, the display will default to user-defined messages. Any high priority event driven message will automatically override the default message and appear on the display.

1.5USING THE RELAY 1.5.1 FACEPLATE KEYPAD

Display messages are organized into pages under the following headings: actual values, settings, commands, and targets. The MENU key navigates through these pages. Each heading page is broken down further into logical subgroups.

The MESSAGE keys navigate through the subgroups. The VALUE keys scroll increment or decrement numerical setting values when in programming mode. These keys also scroll through alphanumeric values in the text edit mode. Alternatively, values may also be entered with the numeric keypad.

The decimal key initiates and advance to the next character in text edit mode or enters a decimal point. The HELP key may be pressed at any time for context sensitive help messages. The ENTER key stores altered setting values.

1.5.2 MENU NAVIGATION

Press the MENU key to select the desired header display page (top-level menu). The header title appears momentarily followed by a header display page menu item. Each press of the MENU key advances through the following main heading pages:

• Actual values.

• Settings.

• Commands.

• Targets.

• User displays (when enabled).

1.5.3 MENU HIERARCHY

The setting and actual value messages are arranged hierarchically. The header display pages are indicated by double scroll bar characters (), while sub-header pages are indicated by single scroll bar characters (). The header display pages represent the highest level of the hierarchy and the sub-header display pages fall below this level. The MESSAGE UP and DOWN keys move within a group of headers, sub-headers, setting values, or actual values. Continually pressing the MESSAGE RIGHT key from a header display displays specific information for the header category. Conversely, continually pressing the MESSAGE LEFT key from a setting value or actual value display returns to the header display.

To put the relay in the “Programmed” state, press either of the VALUE keys once and then press ENTER. The faceplate Trouble LED will turn off and the In Service LED will turn on. The settings for the relay can be programmed manually (refer to Chapter 5) via the faceplate keypad or remotely (refer to the EnerVista UR Setup help file) via the EnerVista UR Setup software interface.

1.5.5 RELAY PASSWORDS

It is recommended that passwords be set up for each security level and assigned to specific personnel. There are two user password security access levels, COMMAND and SETTING:

1. COMMAND

The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the following operations:

• change state of virtual inputs

• clear event records

• clear oscillography records

• operate user-programmable pushbuttons

2. SETTING

The SETTING access level allows the user to make any changes to any of the setting values.

See the Changing Settings section in Chapter 4 for complete instructions on setting up security level passwords.

1.5.6 FLEXLOGIC™ CUSTOMIZATION

FlexLogic™ equation editing is required for setting up user-defined logic for customizing the relay operations. See the FlexLogic™ section in Chapter 5 for additional details.

1.5.7 COMMISSIONING

The F35 requires a minimum amount of maintenance when it is commissioned into service. Since the F35 is a microprocessor-based relay, its characteristics do not change over time. As such, no further functional tests are required.

Furthermore, the F35 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7 for details). However, it is recommended that F35 maintenance be scheduled with other system maintenance. This maintenance may involve the in-service, out-of-service, or unscheduled maintenance.

In-service maintenance:

1. Visual verification of the analog values integrity such as voltage and current (in comparison to other devices on the corresponding system).

2. Visual verification of active alarms, relay display messages, and LED indications.

3. LED test.

4. Visual inspection for any damage, corrosion, dust, or loose wires.

5. Event recorder file download with further events analysis.

Out-of-service maintenance:

1. Check wiring connections for firmness.

2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated test equipment is required.

3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay settings schedule).

4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the system functional testing.

5. Visual inspection for any damage, corrosion, or dust.

6. Event recorder file download with further events analysis.

7. LED Test and pushbutton continuity check.

Unscheduled maintenance such as during a disturbance causing system interruption:

1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements.

If it is concluded that the relay or one of its modules is of concern, contact GE Multilin for prompt service.

2 PRODUCT DESCRIPTION 2.1 INTRODUCTION

2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW

The F35 Multiple Feeder Protection System is a microprocessor based relay designed for the protection of up to five feeders with busbar voltage measurement or up to six feeders without busbar voltage.

Overcurrent and undervoltage protection, breaker recloser, underfrequency, fault diagnostics, and RTU functions are provided. The F35 provides phase, neutral/ground, instantaneous and time overcurrent protection. The time overcurrent function provides multiple curve shapes or FlexCurve™ for optimum co-ordination.

Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total waveform RMS magnitude, or as fundamental frequency only RMS magnitude and angle (phasor). Voltage harmonics and THD metering are also included with the relay.

Diagnostic features include a sequence of records capable of storing 1024 time-tagged events. The internal clock used for time-tagging can be synchronized with an IRIG-B signal or via the SNTP protocol over the Ethernet port. This precise time stamping allows the sequence of events to be determined throughout the system. Events can also be programmed (via FlexLogic™ equations) to trigger oscillography data capture which may be set to record the measured parameters before and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and simplify report generation in the event of a system fault.

A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual values. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and engineering staff. All serial ports use the Modbus

RTU protocol. The RS485 ports may be connected to system computers with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules include a 10Base-F Ethernet interface which can be used to provide fast, reliable communications in noisy environments. Another option provides two 10Base-F fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus TCP, and TFTP protocols, and allows access to the relay via any standard web browser (F35 web pages). The IEC 608705-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.

The F35 IEDs use flash memory technology which allows field upgrading as new features are added. The following Single line diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.

Maximum fiber segment length calculation:

The maximum fiber segment length between two adjacent switches or between a switch and a device is calculated as follows. First, calculate the optical power budget (OPB) of each device using the manufacturer’s data sheets.

where OPB = optical power budget, P and P

= receiver sensitivity.

The worst case optical power budget (OPB lated by taking the lower of the two calculated power budgets, subtracting 1 dB for LED aging, and then subtracting the total insertion loss. The total insertion loss is calculated by multiplying the number of connectors in each single fiber path by 0.5 dB. For example, with a single fiber cable between the two devices, there will be a minimum of two connections in either transmit or receive fiber paths for a total insertion loss of 1db for either direction:

The worst-case optical power budget between two type 2T or 2S modules using a single fiber cable is:

To calculate the maximum fiber length, divide the worst-case optical power budget by the cable attenuation per unit distance specified in the manufacturer data sheets. For example, typical attenuation for 62.5/125 μm glass fiber optic cable is approxi- mately 2.8 dB per km. In our example, this would result in the following maximum fiber length:

These power budgets are calculated from the manufacturer’s worst-case transmitter power and worst case receiver sensitivity.

The power budgets for the 1300 nm ELED are calculated from the manufacturer's transmitter power and receiver sensitivity at ambient temperature. At extreme temperatures these values deviate based on component tolerance. On average, the output power decreases as the temperature is increased by a factor 1dB / 5°C.

a) HORIZONTAL UNITS

The F35 Multiple Feeder Protection System is available as a 19-inch rack horizontal mount unit with a removable faceplate. The faceplate can be specified as either standard or enhanced at the time of ordering. The enhanced faceplate contains additional user-programmable pushbuttons and LED indicators.

The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The faceplate is hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting to access the keypad or RS232 communications port.

The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent equipment.

The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws supplied with the relay.

3.1.2 MODULE WITHDRAWAL AND INSERTION

Module withdrawal and insertion may only be performed when control power has been removed from the unit. Inserting an incorrect module type into a slot may result in personal injury, damage to the unit or connected equipment, or undesired operation!

Proper electrostatic discharge protection (for example, a static strap) must be used when coming in contact with modules while the relay is energized!

The relay, being modular in design, allows for the withdrawal and insertion of modules. Modules must only be replaced with like modules in their original factory configured slots.

The enhanced faceplate can be opened to the left, once the thumb screw has been removed, as shown below. This allows for easy accessibility of the modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and allows easy access to all modules in the F35.

NOTE

Figure 3–8: UR MODULE WITHDRAWAL AND INSERTION (ENHANCED FACEPLATE)

The standard faceplate can be opened to the left, once the sliding latch on the right side has been pushed up, as shown below. This allows for easy accessibility of the modules for withdrawal.

Figure 3–9: UR MODULE WITHDRAWAL AND INSERTION (STANDARD FACEPLATE)

To properly remove a module, the ejector/inserter clips, located at the top and bottom of each module, must be pulled simultaneously. Before performing this action, control power must be removed from the relay. Record the original location of the module to ensure that the same or replacement module is inserted into the correct slot. While modules with current input provide automatic shorting of external CT circuits, for CT/VT modules it is recommended to short/isolate external circuits accordingly for maximum safety.

To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/ inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

All CPU modules except the 9E are equipped with 10/100Base-T or 100Base-F Ethernet connectors. These connectors must be individually disconnected from the module before it can be removed from the chassis.

WARNING

3.1 DESCRIPTION 3 HARDWARE

The 4.0x release of the F35 relay includes new hardware modules.The new CPU modules are specified with codes 9E and higher. The new CT/VT modules are specified with the codes 8F and higher.

The new CT/VT modules can only be used with new CPUs; similarly, old CT/VT modules can only be used with old CPUs. To prevent hardware mismatches, the new modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and DSP module label colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module, the relay will not function and a

DSP ERROR or HARDWARE MISMATCH error will be dis-

played.

All other input and output modules are compatible with the new hardware. Firmware versions 4.0x and higher are only compatible with the new hardware modules. Previous versions of the firmware (3.4x and earlier) are only compatible with the older hardware modules.

3.1.3 REAR TERMINAL LAYOUT

The relay follows a convention with respect to terminal number assignments which are three characters long assigned in order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following figure for an example of rear terminal assignments.

3-8 F35 Multiple Feeder Protection System GE Multilin

Do not touch any rear terminals while the relay is energized!

Figure 3–10: REAR TERMINAL VIEW

3 HARDWARE 3.1 DESCRIPTION

Figure 3–11: EXAMPLE OF MODULES IN F AND H SLOTS

The torque used to connect the terminal blocks to the back of the relay chassis (screws a, b, c shown) is 9 inch-pounds. For the connections to the terminal blocks (rows 1 to 8), use a minimum of 17 inch-pounds. During manufacturing, the power supply and CPU modules are installed in slots B and D of the chassis with 13 inch-pounds of torque on the screws at the top and bottom of the modules.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused by high peak voltage transients, radio frequency interference (RFI), and electromagnetic interference (EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one minute.

3.2.3 CONTROL POWER

Control power supplied to the relay must be connected to the matching power supply range of the relay. If the voltage is applied to the wrong terminals, damage may occur.

The F35 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well known to be subject to deterioration over time if voltage is not applied periodically. Deterioration can be avoided by powering the relays up once a year.

The power supply module can be ordered for two possible voltage ranges, with or without a redundant power option. Each range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical specifica- tions section of chapter 2 for additional details):

• Low (LO) range: 24 to 48 V (DC only) nominal.

• High (HI) range: 125 to 250 V nominal.

The power supply module provides power to the relay and supplies power for dry contact input connections.

The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the Typical wiring diagram earlier). The critical failure relay is a form-C device that will be energized once control power is applied and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a critical failure (see the Self-test errors section in chapter 7) or control power is lost, the relay will de-energize.

For high reliability systems, the F35 has a redundant option in which two F35 power supplies are placed in parallel on the bus. If one of the power supplies become faulted, the second power supply will assume the full load of the relay without any interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay of the module will also indicate a faulted power supply.

When using an SH/SL power supply module or a F35 with the HardFiber system, before powering off the F35, save data in the compact flash memory using Commands > Relay Maintenance > Save Non-Volatile Data. When not saved or the relay loses power, up to the last two minutes of data is not saved to the compact flash memory.

3.2.4 CT/VT MODULES

A CT/VT module may have voltage inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive. Channels 1 and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6 are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C.

Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and ground, and are labelled as ground current (IG).

Verify that the connection made to the relay nominal current of 1 A or 5 A matches the secondary rating of the connected CTs. Unmatched CTs may result in equipment damage or inadequate protection.

CT/VT modules may be ordered with a standard ground current input that is the same as the phase current input. Each AC current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to 50000 A primaries and 1 A or 5 A secondaries may be used.

CT/VT modules with a sensitive ground input are also available. The ground CT input of the sensitive ground modules is ten times more sensitive than the ground CT input of standard CT/VT modules. However, the phase CT inputs and phase VT inputs are the same as those of regular CT/VT modules.

The above modules are available with enhanced diagnostics. These modules can automatically detect CT/VT hardware failure and take the relay out of service.

CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram.

3.2.5 PROCESS BUS MODULES

The F35 can be ordered with a process bus interface module. This module is designed to interface with the GE Multilin HardFiber system, allowing bi-directional IEC 61850 fiber optic communications with up to eight HardFiber merging units, known as Bricks. The HardFiber system has been designed to integrate seamlessly with the existing UR-series applications, including protection functions, FlexLogic™, metering, and communications.

The IEC 61850 process bus system offers the following benefits.

• Drastically reduces labor associated with design, installation, and testing of protection and control applications using the F35 by reducing the number of individual copper terminations.

• Integrates seamlessly with existing F35 applications, since the IEC 61850 process bus interface module replaces the traditional CT/VT modules.

• Communicates using open standard IEC 61850 messaging.

For additional details on the HardFiber system, refer to GE publication GEK-113500: HardFiber System Instruction Manual.

3.2.6 CONTACT INPUTS AND OUTPUTS

Every contact input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight rows in total. A given row of three terminals may be used for the outputs of one relay. For example, for form-C relay outputs, the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A output, there are options of using current or voltage detection for feature supervision, depending on the module ordered. The terminal configuration for contact inputs is different for the two applications.

The contact inputs are grouped with a common return. The F35 has two versions of grouping: four inputs per common return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used. The four inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs sharing one common. If the inputs must be isolated per row, then two inputs per common return should be selected (4D module).

The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that may be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot position and row number. However, since there are two contact inputs per row, these names are assigned by module slot position, row number, and column position.

Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector whose output is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On = 1” when the current is above about 1 to 2.5 mA, and the current monitor is set to “On = 1” when the current exceeds about 80 to 100 mA. The voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in the output contact until an external contact has interrupted current flow.

Block diagrams are shown below for form-A and solid-state relay outputs with optional voltage monitor, optional current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs.

NOTE

Figure 3–16: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING

The operation of voltage and current monitors is reflected with the corresponding FlexLogic™ operands (CONT OP # VON,

CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical application of

the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the control command.

Refer to the Digital elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be applied for breaker trip circuit integrity monitoring.

Relay contacts must be considered unsafe to touch when the unit is energized! If the relay contacts need to be used for low voltage accessible applications, it is the customer’s responsibility to ensure proper insulation levels!

USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS

For form-A and solid-state relay output contacts internally equipped with a voltage measuring cIrcuit across the contact, the circuit has an impedance that can cause a problem when used in conjunction with external high input impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the form-A contact as being closed after it has closed and subsequently opened, when measured as an impedance.

The solution to this problem is to use the voltage measuring trigger input of the relay test set, and connect the formA contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the form-A contact or the resistor can be used to monitor the state of the output.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number sign “#” appears, substitute the contact number

NOTICE

When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the FlexLogic™ operand driving the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in situations when the element initiating the contact output is bouncing, at values in the region of the pickup value).

CONTACT INPUTS:

A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power supply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply module. When a dry contact closes, a current of 1 to 3 mA will flow through the associated circuit.

A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source must be connected to the relay common (negative) terminal of each contact group. The maximum external source voltage for this arrangement is 300 V DC.

The voltage threshold at which each group of four contact inputs will detect a closed contact input is programmable as 17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

Figure 3–19: DRY AND WET CONTACT INPUT CONNECTIONS

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

Contact outputs may be ordered as form-a or form-C. The form-A contacts may be connected for external circuit supervision. These contacts are provided with voltage and current monitoring circuits used to detect the loss of DC voltage in the circuit, and the presence of DC current flowing through the contacts when the form-A contact closes. If enabled, the current monitoring can be used as a seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld the output contacts.

GENERAL APPLICATION CONSIDERATIONS:

There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend using an external DC supply.

Contacts outputs of protective relays, auxiliary contacts from breakers, disconnectors and other devices, are generally connected to contacts inputs of protective relays. In some situations, the contact outputs of some protective relays can have high impedance connected across it. When such a contact output is connected across a F35 contact input, it can spuriously operate the F35 input even when the output is open, if there is a substantial distributed capacitance (represented by C1) present in the wiring between the output and the F35 input and the debounce time setting in the F35 relay is low enough. This false assertion of the contact input, when there is inadvertent ground present at the DC positive terminal, can be prevented by inserting a resistor across the F35 input.

3-20 F35 Multiple Feeder Protection System GE Multilin

3 HARDWARE 3.2 WIRING

The following figure shows a typical DC circuit, with battery ground detection, of contact input. The contact output has parallel impedance across it (represented by R1).

Figure 3–20: TYPICAL CONTACT INPUT DC CIRCUIT

The presence of the impedance path (R1) across the contact output allows the stray (distributed) capacitance C1 to charge as shown, thus developing a voltage across the contact input enough to momentarily operate the input while the capacitance discharges in the presence of DC ground on the positive terminal of the battery.

The duration of the discharge depends on the value of the distributed capacitance, the initial voltage of the distributed capacitance, and the input impedance of the contact input. If the duration is greater than the debounce time setting, then the contact input operates.

The application example that follows describes how to mitigate this problem by connecting a resistor across the contact input, as shown in the next figure, or by adjusting the debounce time setting to a value greater than the discharge time to prevent spurious operation of the contact input only if the voltage (with output open) across the contact input due to trickle current is less than the threshold voltage. This operation of contact inputs also can be prevented by using the Auto-Burnish contact inputs or contact inputs with active impedance.

APPLICATION EXAMPLE:

This example is for illustrative purposes only and the calculations present the worst-case scenario. In practice, the value of debounce time can be lower.

Contact input ON state impedance used in the calculation of the discharge period is based on the following table.

Assume an initial voltage across the stray capacitance "Vinitial" = 19 V (Vthreshold - 65 V), where Vthreshold = 84 V. The initial voltage Vinitial depends on values of impedance of R1 and contact inputs when the contact input is OFF (non-activated state).

Therefore, discharge time constant (τ) =50 kΩ *0.1 μF = 5 ms.

Discharge period t is calculated from the following equation:

Vthreshold = (Vbatt - VInitial) *e^ (-t/τ)

84 = -149 *e^ (t/0.005) (EQ 3.1)

T = -0.005 * ln (84/149) = 0.0029 s

Therefore, in this example the contact inputs operate.

To prevent this operation, the debounce time must be increased to 4 ms (set debounce time as per the following table) or insert a resistor less than or equal to "R" as calculated later.

Table 3–4: TYPICAL DEBOUNCE TIME SETTING

STRAY CAPACITANCE (μF) BATTERY VOLTAGE (V) DEBOUNCE TIME (MS)

0.1 130 4

0.2 130 6

0.05 250 3

0.1 250 6

0.2 250 11

The value of this resistor "R" is calculated as follows:

1. Determine the minimum voltage (V threshold) required to turn on the input. This is determined by direct measurement or referenced in the input specifications.

2. Calculate the resistance necessary to limit the voltage to 1/3 V threshold (when the contact is OFF, the non-activated state) as follows:

R = (Vthreshold / 3) / (2 mA) (EQ 3.2)

The 2 mA current is used in case the contact input is connected across the GE Form A contact output with voltage monitoring. Otherwise use the amperage of the active circuit connected to the contact input when its contact output is open and the voltage across the contact input is third trigger threshold to calculate the resistor value.

3. When the contact is ON (operate state), the battery voltage appears across the resistor. The wattage rating of the resistor is then:

PR = 1.3 * (Vbatt) ^2 / R Watts (EQ 3.3)

4. Applying the following equation to our example:

R = 84 V / 3*(1 / 2 mA) = 14 kΩ

PR = 1.57 Watts (EQ 3.4)

5. Calculating the voltage across the contact input with the Burden Resistor, Voltage across the contact Input:

Vresistor = 2 mA * 14 Kohm = 28 V

Vresistor < contact input threshold (84 V) (EQ 3.5)

In conclusion, in this example, the contact input does NOT operate falsely with the Burden Resistor across its input AND when a battery ground is present.

USE OF CONTACT INPUTS WITH AUTO-BURNISHING:

The contact inputs sense a change of the state of the external device contact based on the measured current. When external devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to various types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to establish circuit continuity – an impulse of higher than normal current can accomplish this.

The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The impulse will have a 5 second delay after a contact input changes state.

Figure 3–22: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with autoburnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to 50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the contacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts when external device contact bouncing is over.

Another important difference between the auto-burnishing input module and the regular input modules is that only two contact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Contact Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Consequently, the threshold voltage setting is also defined per group of two contact inputs.

NOTE

The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP switch for each contact, for a total of 16 inputs.

Figure 3–23: AUTO-BURNISH DIP SWITCHES

The auto-burnish circuitry has an internal fuse for safety purposes. During regular maintenance, the auto-burnish functionality can be checked using an oscilloscope.

USE OF CONTACT INPUTS WITH ACTIVE IMPEDANCE:

Contact inputs susceptible to parasitic capacitance caused by long cable runs affected by switching surges from external circuits can result in inadvertent activation of contact inputs with the external contact open. In this case, GE recommends using the digital I/O module with active impedance circuit.

Active impedance contact input can tolerate external cable capacitance of up to 0.2 µF, without entering the ON state for more than 2 ms. The contact input debounce time can still be set above 2 ms for added security to prevent contact input activations cause by external transient ON states.

An active impedance contact input is normally in Low impedance mode during OFF contact state (non-activated condition). During Low impedance state contact input impedance is maintained at 10 K Ohms impedance to allow fast discharge of the stray capacitance of the long cables.

When the contact input voltage exceeds the set threshold, active impedance maintains 10 K Ohms impedance value. If voltage starts rapidly decreasing, this indicates that stray capacitance is being discharged through the contact input. If, however, voltage stabilizes above the set threshold, the input impedance is switched to High impedance mode of 100 K Ohms. This value reduces the input current to <3 mA, and contact input switched to the ON state (operated state).

The figure shows the active impedance contact input V-I characteristic. Different thresholds with their corresponding characteristics are shown by color. The contact input is in the ON (operated) state if the input voltage is to the right of the colored threshold band (+/-10% tolerance), and the contact input is in the OFF (non-activated) state when input voltage is to the left of the band. A contact input is in LOW state during non-operated system condition, and actively switches to HIGH state upon detection of input voltage above the settable threshold.

3.2.7 TRANSDUCER INPUTS/OUTPUTS

Transducer input modules can receive input signals from external dcmA output transducers (dcmA In) or resistance temperature detectors (RTD). Hardware and software is provided to receive signals from these external transducers and convert these signals into a digital format for use as required.

Transducer output modules provide DC current outputs in several standard dcmA ranges. Software is provided to configure virtually any analog quantity used in the relay to drive the analog outputs.

Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three terminals per row with a total of eight rows. A given row may be used for either inputs or outputs, with terminals in column "a" having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/ output channel, the name of the channel is assigned using the module slot position and row number.

Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs require a twisted-pair shielded cable, where the shield is grounded at one end only. The figure below illustrates the trans-

ducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that may be ordered for the relay.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

A 9-pin RS232C serial port is located on the F35 faceplate for programming with a personal computer. All that is required to use this interface is a personal computer running the EnerVista UR Setup software provided with the relay. Cabling for the RS232 port is shown in the following figure for both 9-pin and 25-pin connectors.

The baud rate for this port is fixed at 19200 bps.

In addition to the faceplate RS232 port, the F35 provides two additional communication ports or a managed six-port Ethernet switch, depending on the installed CPU module.

For the 9J/9K CPU, the 10/100Base-T port has the lowest priority and is only active if both CH1 and CH2 fiber links are down. Installation of the 10/100Base-T Ethernet cable at the same time as the CH1 and/or CH2 100Base-F fiber cables does not affect the communication over the CH1 or CH2 fiber ports.

b) RS485 PORTS

RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. Through the use of these ports, continuous monitoring and control from a remote computer, SCADA system or PLC is possible.

To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–” terminals connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared

reference, or common voltage. This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the F35 COM terminal (#3); others function correctly only if the common wire is connected to the F35 COM terminal, but insulated from the shield.

To avoid loop currents, the shield should be grounded at only one point. If other system considerations require the shield to be grounded at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding point. Each relay should also be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters to have more than 32 relays on a single channel. Star or stub connections should be avoided entirely.

Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communication ports. An isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all equipment should have similar transient protection devices installed.

Both ends of the RS485 circuit should also be terminated with an impedance as shown below.

The fiber optic communication ports allow for fast and efficient communications between relays at 10 Mbps or 100 Mbps. Optical fiber may be connected to the relay supporting a wavelength of 820 nm in multi-mode or 1310 nm in multi-mode and single-mode. The 10 Mbps rate is available for CPU modules 9G and 9H; 100Mbps is available for modules 9H, 9J, 9K, 9L, 9M, and 9N. The 9H, 9K, and 9M modules have a second pair of identical optical fiber transmitter and receiver for redundancy.

The optical fiber sizes supported include 50/125 µm, 62.5/125 µm and 100/140 µm for 10 Mbps. The fiber optic port is designed such that the response times will not vary for any core that is 100 µm or less in diameter, 62.5 µm for 100 Mbps. For optical power budgeting, splices are required every 1 km for the transmitter/receiver pair. When splicing optical fibers, the diameter and numerical aperture of each fiber must be the same. In order to engage or disengage the ST type connector, only a quarter turn of the coupling is required.

IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices within 1 millisecond. The IRIG time code formats are serial, width-modulated codes which can be either DC level shifted or amplitude modulated (AM). Third party equipment is available for generating the IRIG-B signal; this equipment may use a GPS satellite system to obtain the time reference so that devices at different geographic locations can also be synchronized.

Figure 3–29: IRIG-B CONNECTION

The IRIG-B repeater provides an amplified DC-shift IRIG-B signal to other equipment. By using one IRIG-B serial connection, several UR-series relays can be synchronized. The IRIG-B repeater has a bypass function to maintain the time signal even when a relay in the series is powered down.

Figure 3–30: IRIG-B REPEATER

Using an amplitude modulated receiver will cause errors up to 1 ms in event time-stamping.

3.3DIRECT INPUT/OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION

The F35 direct inputs and outputs feature makes use of the type 7 series of communications modules. These modules are also used by the L90 Line Differential Relay for inter-relay communications. The direct input and output feature uses the communications channels provided by these modules to exchange digital state information between relays. This feature is available on all UR-series relay models except for the L90 Line Differential relay.

The communications channels are normally connected in a ring configuration as shown below. The transmitter of one module is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver of the next module in the ring. This is continued to form a communications ring. The figure below illustrates a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx, and UR4-Tx to UR1-Rx. A maximum of 16 URs can be connected in a single ring

Figure 3–31: DIRECT INPUT AND OUTPUT SINGLE CHANNEL CONNECTION

IRC modules with protocol C37.94 and G.703 are designed for back-to-back communication connections, so the ring configuration shown in the previous figure does not apply. To establish inter-relay communication in more than two URs, you need to have two channel IRC module and enable DIRECT I/O CHANNEL CROSSOVER function in all relays, as shown in the next figure. This configuration can be expanded to 16 URs, and this configuration does not provide redundancy ring since both channels are made into single ring by the channel crossover function. As per the figure Typical Pin Interconnection between Two G.703 Interfaces later in this chapter, the clock is supplied typically by multiplexer (MUX) and all URs are in Loop Timing Mode. If there is no MUX, then UR1 and UR3 can be in Internal Timing Mode and UR2 and UR4 can be in Loop Timing Mode. That is, connected channels must have opposite timing modes.

The interconnection for dual-channel Type 7 communications modules is shown below. Two channel modules allow for a redundant ring configuration. That is, two rings can be created to provide an additional independent data path. The required connections are: UR1-Tx1 to UR2-Rx1, UR2-Tx1 to UR3-Rx1, UR3-Tx1 to UR4-Rx1, and UR4-Tx1 to UR1-Rx1 for the first ring; and UR1-Tx2 to UR4-Rx2, UR4-Tx2 to UR3-Rx2, UR3-Tx2 to UR2-Rx2, and UR2-Tx2 to UR1-Rx2 for the second ring.

Figure 3–33: DIRECT INPUT AND OUTPUT DUAL CHANNEL CONNECTION

The following diagram shows the connection for three UR-series relays using two independent communication channels. UR1 and UR3 have single type 7 communication modules; UR2 has a dual-channel module. The two communication channels can be of different types, depending on the Type 7 modules used. To allow the direct input and output data to cross- over from channel 1 to channel 2 on UR2, the

DIRECT I/O CHANNEL CROSSOVER setting should be “Enabled” on UR2. This

forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

The interconnection requirements are described in further detail in this section for each specific variation of type 7 communications module. These modules are listed in the following table. All fiber modules use ST type connectors.

The following figure shows the typical pin interconnection between two G.703 interfaces. For the actual physical arrangement of these pins, see the Rear terminal assignments section earlier in this chapter. All pin interconnections are to be maintained for a connection to a multiplexer.

Figure 3–38: TYPICAL PIN INTERCONNECTION BETWEEN TWO G.703 INTERFACES

Pin nomenclature may differ from one manufacturer to another. Therefore, it is not uncommon to see pinouts numbered TxA, TxB, RxA and RxB. In such cases, it can be assumed that “A” is equivalent to “+” and “B” is equivalent to “–”.

b) G.703 SELECTION SWITCH PROCEDURES

1. Remove the G.703 module (7R or 7S). The ejector/inserter clips located at the top and at the bottom of each module, must be pulled simultaneously in order to release the module for removal. Before performing this action, control power must be removed from the relay. The original location of the module should be recorded to help ensure that the same or replacement module is inserted into the correct slot.

2. Remove the module cover screw.

3. Remove the top cover by sliding it towards the rear and then lift it upwards.

4. Set the timing selection switches (channel 1, channel 2) to the desired timing modes.

5. Replace the top cover and the cover screw.

6. Re-insert the G.703 module. Take care to ensure that the correct module type is inserted into the correct slot position.

The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

SWITCHES FUNCTION

S1 OFF → octet timing disabled

S5 and S6 S5 = OFF and S6 = OFF → loop timing mode

c) G.703 OCTET TIMING

If octet timing is enabled (on), this 8 kHz signal will be asserted during the violation of bit 8 (LSB) necessary for connecting to higher order systems. When F35s are connected back to back, octet timing should be disabled (off).

d) G.703 TIMING MODES

There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default).

• Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in

the internal timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set for octet timing (S1 = OFF) and timing mode to internal timing (S5 = ON and S6 = OFF).

• Loop Timing Mode: The system clock is derived from the received line signal. Therefore, the G.703 timing selection

should be in loop timing mode for connections to higher order systems. For connection to a higher order system (URto-multiplexer, factory defaults), set to octet timing (S1 = ON) and set timing mode to loop timing (S5 = OFF and S6 = OFF).

ON → octet timing 8 kHz

S5 = ON and S6 = OFF → internal timing mode S5 = OFF and S6 = ON → minimum remote loopback mode S5 = ON and S6 = ON → dual loopback mode

e) G.703 TEST MODES

In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any

processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs, passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing source is expected to be from the G.703 line side of the interface.

Figure 3–40: G.703 MINIMUM REMOTE LOOPBACK MODE

In dual loopback mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/ transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module. Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing. One source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the interface.

3.3.5 RS422 INTERFACE

a) DESCRIPTION

There are two RS422 inter-relay communications modules available: single-channel RS422 (module 7T) and dual-channel RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 24 twisted shielded pair cable is recommended for external connections. These modules are protected by optically-isolated surge suppression devices.

The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:

• Site 1: Terminate shield to pins 6a or 7b or both.

• Site 2: Terminate shield to COM pin 2b.

The clock terminating impedance should match the impedance of the line.

The following figure shows the typical pin interconnection between two single-channel RS422 interfaces installed in slot W. All pin interconnections are to be maintained for a connection to a multiplexer.

b) TWO-CHANNEL APPLICATION VIA MULTIPLEXERS

The RS422 interface may be used for single channel or two channel applications over SONET/SDH or multiplexed systems. When used in single-channel applications, the RS422 interface links to higher order systems in a typical fashion observing transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two-channel applications, certain criteria must be followed since there is one clock input for the two RS422 channels. The system will function correctly if the following connections are observed and your data module has a terminal timing feature. Terminal timing is a common feature to most synchronous data units that allows the module to accept timing from an external source. Using the terminal timing feature, two channel applications can be achieved if these connections are followed: The send timing outputs from the multiplexer (data module 1), will connect to the clock inputs of the UR–RS422 interface in the usual fashion. In addition, the send timing outputs of data module 1 will also be paralleled to the terminal timing inputs of data module 2. By using this configuration, the timing for both data modules and both UR–RS422 channels will be derived from a single clock source. As a result, data sampling for both of the UR–RS422 channels will be synchronized via the send timing leads on data module 1 as shown below. If the terminal timing feature is not available or this type of connection is not desired, the G.703 interface is a viable option that does not impose timing restrictions.

Figure 3–44: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the F35 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been omitted in the figure above since they may vary depending on the manufacturer.

c) TRANSMIT TIMING

The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is important to confirm clock and data transitions to ensure proper system operation. For example, the following figure shows the positive edge of the Tx clock in the center of the Tx data bit.

d) RECEIVE TIMING

The RS422 interface utilizes NRZI-MARK modulation code and; therefore, does not rely on an Rx clock to recapture data. NRZI-MARK is an edge-type, invertible, self-clocking code.

To recover the Rx clock from the data-stream, an integrated DPLL (digital phase lock loop) circuit is utilized. The DPLL is driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a data clock that can be used as the SCC (serial communication controller) receive clock.

3.3.6 RS422 AND FIBER INTERFACE

The following figure shows the combined RS422 plus Fiber interface configuration at 64K baud. The 7L, 7M, 7N, 7P, and 74 modules are used in two-terminal with a redundant channel or three-terminal configurations where channel 1 is employed via the RS422 interface (possibly with a multiplexer) and channel 2 via direct fiber.

AWG 24 twisted shielded pair is recommended for external RS422 connections and the shield should be grounded only at one end. For the direct fiber channel, power budget issues should be addressed properly.

When using a laser interface, attenuators can be necessary to ensure that you do not exceed maximum optical input power to the receiver.

3.3.8 IEEE C37.94 INTERFACE

The UR-series IEEE C37.94 communication modules (modules types 2G, 2H, 76, and 77) are designed to interface with IEEE C37.94 compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and output applications for firmware revisions 3.30 and higher. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94 communication modules are either 64 kbps (with n fixed at 1) or 128 kbps (with n fixed at 2). The frame is a valid International Telecommunications Union (ITUT) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:.

• IEEE standard: C37.94 for 1 × 128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2 × 64 kbps opti-

cal fiber interface (for 76 and 77 modules).

• Fiber optic cable type: 50 mm or 62.5 mm core diameter optical fiber.

• Fiber optic mode: multi-mode.

• Fiber optic cable length: up to 2 km.

• Fiber optic connector: type ST.

• Wavelength: 830 ±40 nm.

• Connection: as per all fiber optic connections, a Tx-to-Rx connection is required.

The UR-series C37.94 communication module can be connected directly to any compliant digital multiplexer that supports the IEEE C37.94 standard as shown below.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a non-compliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard, as shown below.

In 2008, GE Grid Solutions released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60 and higher, the module can be identified with "Rev D" printed on the module and is to be used on all ends of F35 communication for two and three terminal applications. Failure to use it at all ends results in intermittent communication alarms. For customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.

842753A1.CDR

The UR-series C37.94 communication module has six switches that are used to set the clock configuration. The functions of these control switches is shown below.

For the internal timing mode, the system clock is generated internally. therefore, the timing switch selection should be internal timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.

For the looped timing mode, the system clock is derived from the received line signal. Therefore, the timing selection should be in loop timing mode for connections to higher order systems.

The IEEE C37.94 communications module cover removal procedure is as follows:

1. Remove the IEEE C37.94 module (type 2G, 2H, 76 or 77 module):

The ejector/inserter clips located at the top and at the bottom of each module, must be pulled simultaneously in order to release the module for removal. Before performing this action, control power must be removed from the relay. The original location of the module should be recorded to help ensure that the same or replacement module is inserted into the correct slot.

2. Remove the module cover screw.

3. Remove the top cover by sliding it towards the rear and then lift it upwards.

4. Set the timing selection switches (channel 1, channel 2) to the desired timing modes (see description above).

5. Replace the top cover and the cover screw.

6. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot

position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

3.3.9 C37.94SM INTERFACE

The UR-series C37.94SM communication modules (2A and 2B) are designed to interface with modified IEEE C37.94 compliant digital multiplexers or IEEE C37.94 compliant interface converters that have been converted from 820 nm multi-mode fiber optics to 1300 nm ELED single-mode fiber optics. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94SM communication module is 64 kbps only with n fixed at 1. The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:

• Emulated IEEE standard: emulates C37.94 for 1 × 64 kbps optical fiber interface (modules set to n = 1 or 64 kbps).

• Fiber optic cable type: 9/125 μm core diameter optical fiber.

• Fiber optic mode: single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver.

• Fiber optic cable length: up to 10 km.

• Fiber optic connector: type ST.

• Wavelength: 1300 ±40 nm.

• Connection: as per all fiber optic connections, a Tx-to-Rx connection is required.

The UR-series C37.94SM communication module can be connected directly to any compliant digital multiplexer that supports C37.94SM as shown below.

It can also can be connected directly to any other UR-series relay with a C37.94SM module as shown below.

In 2008, GE Grid Solutions released revised modules 2A and 2B for C37.94SM communication to enable multi-ended fault location functionality with firmware 5.60 release and higher.
