ADDENDUM

This addendum contains information that relates to the N60 Network Stability and Synchrophasor Measurement System, version 5.5x. This addendum lists a number of information items that appear in the instruction manual GEK113419B (revision S3) but are not included in the current N60 operations.

The following functions and items are not yet available with the current version of the N60 relay:

•N/A. Version 4.0x and higher releases of the N60 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/8VT

-- 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/8VT 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 warni ng sticker stating “Attn.: Ensure C PU 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

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 mod-

ules. Previous versions of the firmware (3.4x and earlier) are only compatible with the older CPU and CT/VT modules.

DSP ERROR or HARDWARE MISMATCH error will be displayed.

1.2 UR OVERVIEW 1 GETTING STARTED

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR

Historically, substation protection, control, and metering functions were performed wi th electromechanical equip ment. 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 th ese technologi es required expensive cabling a nd auxiliary equipment to produce functioning systems.

Recently, digital electronic equipment has begun to p rovide 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 pro ducts 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 r eductions. This requires placing eve n more functions within the IEDs.

Users of power equipment are also interested in reducing cost by improving power quality and pe rsonnel 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 tr ansfer rates required by moder n 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 a s programmable logic gates, timers, and latches for control features.

Input elements accept a variety of analog or digital signals from the field. The UR isol ates and con verts 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.

Operator Interface

827822A2.CDR

b) UR SIGNAL TYPES

The contact inpu t s and output s are digit al signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’ contacts are supported.

The vi rtual 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™ equation s 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 digi tal 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 featu re 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 dev ice 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.

1.2.3 SOFTWARE ARCHITECTURE

The firmware (software embedded in the relay) is designed in functional modules wh ich 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 N60 achieves the same features a s the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for exampl e, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various fun ctionality 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 CT s 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.

1.5.7 COMMISSIONING

The N60 requires a minimum amount of maintenance when it is commissioned into service. Since the N60 is a microprocessor-based relay, its characteristics do not change over time. As such, no further functional tests are required.

Furthermore, the N60 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 N60 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 cor-

responding 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 N60 Network Stability and Synchrophasor Measurement System is a flexible microprocessor-based device intended for development of load shedding and special protection schemes.

Owing to its modular architecture, the N60 can be configured to monitor from one through five three-phase power circuits. The relay provides for variety of metering functions, including: active, reactive and apparent power on a per-phase and three-phase basis; true RMS value, phasors and symmetrical components of currents and voltages; and power factor and frequency. The latter could be measured independently and simultaneously from up to six different signals.

The N60 allows interfacing other analog signals via opti onal transducer modu les to monitor equipmen t temperature, transformer tap positions, weather data, and other information.

In addition to a standard collection of communications protocols that can be exercised simultaneously and independently over a range of communication ports, including the redundant Ethernet port, the relay supports an independent mechanism for direct, fast and secure digital inter-IED communications. This allo ws both reducing wiri ng and development time for all the local connections in a substation, as well as building wide-area protection and control schemes.

Up to 64 on/off signals can be exchanged between any two N60 devices via digital communications. The relays could be configured in rings with up to 16 devices each using direct fiber (C37.94), G.704 and RS422 interfaces. An optional redundant (dual-channel) communication card supports combinations of the three i nterfaces allowing d ifferent physical connections in each channel. Dual-ring communication architecture could be selected for redundancy. Open ring or crossover configurations could be utilized to increase the number of devices in the scheme.

The effective message delivery time depends of number of other N60 devices located between the sending and receiving IEDs. A two-cycle or one-cycle worst-case message delivery times could be comfortably achieved for comparatively large N60 schemes.

Sophisticated self-monitoring and diagnostic functions are incorporated such as the 32-bit CRC, u nreturned messages count or lost packets counts. The N60 supports both multiplexed and direct fiber (up to 100 km) inter-substation connections.

The N60 allows sending and receiving any analog value mea s ured by th e relay using the ded icated inter-IED commu nication mechanisms. Power, voltage and current magnitudes, frequency , transducer inputs and other values can be freely configured for the inter-IED exchanges. The analog values are transmitted with th e eight-bit resolution. Upon reception, any remote analog value could be re-sent, compared with another value or a co nstant threshold, added to or subtracted from other local or remote analog value, subjected to the rate-of-ch ange monitoring, etc. T his powe rful fe ature allow s advan ced applications such as balancing power over wi de areas, or addi ng extra security by comparing local and remote measurements for consistency. It also facilitates simple telemetry.

Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of storing up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16 channels, with programmable content and sampling rate. The internal clock us ed for time-tagging can be synch ronized with a n IRIGB signal or via the SNTP protocol over the Ethernet port. This preci se time stamping allows the sequence o f 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 even t 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 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 10BaseF Ethernet interface which can be used to provide fast, reliable communications in noisy environme nts. Another option provides two 10BaseF fiber optic ports for redundancy. The Ethernet port supports MMS/UCA2, Modbus TCP, and TFTP protoc ols, and allows access to the rel ay via any standard web browser (UR 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 N60 IEDs use flash memory technology which allows field upgrad ing as new features ar e added. T he foll owing Sing le Line Diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.

ETHERNET SWITCH FIBER OPTIC PORTS

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.

OPB P

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, sub-

–=

TMIN()PRMIN()

= transmitter output power,

WORST

) is then calcu-

tracting 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:

Total insertion loss number of connectors 0.5 dB×=

2 0.5 dB×= 1.0 dB=

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

OPB

WORST

OPB 1 dB (LED aging)– total insertion loss–=

10dB 1dB– 1dB– 8dB=

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:

Maximum fiber length

OPB

-------------------------------------------------------

cable loss (in dB/km)

8 dB

---------------------------= 2.8km=

2.8 dB/km

WORST

(in dB)

The customer must use the attenuation specified within the manufacturer data sheets for accurate calculation of the maximum fiber length.

3 HARDWARE 3.1DESCRIPTION 3.1.1 PANEL CUTOUT

The N60 Network Stability and Synchrophasor Measurement 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.

tact 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 sho wn 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 N60.

12A1.CDR

Figure 3–4: 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 3–5: UR MODULE WITHDRAWAL AND INSERTION (STANDARD FACEPLATE)

To properly remo ve 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 r elay. Record the original location of the module to ensure that the same or replacement module is inserted into the correct slot. Modules with current input provide automatic shorting of external CT circuits.

GE Multilin N60 Network Stability and Synchrophasor Measurement System 3-3

3.1 DESCRIPTION 3 HARDWARE

To properly inse rt 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 Ether net connectors. These connectors must be individually disconnected from the module before it can be removed from the chassis.

The 4.0x release of the N60 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.

NOTE

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 p revent hardware mismatches, the new modules ha ve 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 misma tch between the

CPU and CT/VT module, the relay will not function and a played.

DSP ERROR or HARDWARE MISMATCH error will be dis-

All other input and output modules are compatible with the new hardwa re. 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.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused b y high peak voltage transients, radio frequency interference (RFI), and electromagnetic i nterference (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

CAUTION

OCCUR! The N60 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well

known to be subject to deterioration over ti me if voltage is not applied periodically. Deterioration can be

NOTE

avoided by powering the relays up once a year.

The power supply module can be ordered for two possible voltage ranges, with o r withou t a re dun dant po wer optio n. Each range has a dedicated input connection for proper operation. The ra nges 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 conta ct input connections and a critical failure relay (see the

Typical wiring diagram earlier). The critical failure relay is a form-C device that w ill 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 N60 has a redundant option in which two N60 powe r 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.

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).

3.2.4 CT AND VT MODULES

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 me chanism that shorts the input when the mo dule 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.

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. The exact placement of a zero-sequence core balanc e CT to detect ground fault current is shown below. Twi sted-pair

cabling on the zero-sequence CT is recommended.

3.2.5 CONTACT INPUTS AND OUTPUTS

Every digital input/output module has 24 terminal connections. T hey 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, dep ending on the module ordered. The terminal configuration for contact inputs is different for the two applications.

The digital inputs are grouped with a common return. The N60 has two versions of grouping: four inputs per common return and two inputs per common return. When a digital 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 type s (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 ou tput is set to logic “On = 1” when the current in the circuit is above the thre shold 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 curren t monitor can be used to seal-in the output contact until an external contact has interrupted current flow.

The operation of voltage and current monitors is reflected with th e corresponding F lexLogic™ operands (CONT OP # VON,

CONT OP # VOFF, CONT OP # ION, and CONT OP # IOFF) 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

WARNING

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

NOTE

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, w hen 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 th e power supply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across e ither 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 mo dule; wherever a number sign "#" appears, substitute the contact number

NOTE

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 d elay of 10 ms to prevent damage of

CONTACT INPUTS:

A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail sup plied b y th e 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 vol tage 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.

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.

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.

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.

842749A1.CDR

Figure 3–17: 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-burnish ing 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 Digital Input/ Output Module Wiring diagrams). This is beneficial when connecting c ontact inputs to separate voltage sources. Consequently, the threshold voltage setting is also defined per group of two contact inputs.

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

3.2.6 TRANSDUCER INPUTS AND 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 po larity. 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 extern al ground bus be made to terminal 8b. The current outputs require a twisted-pair shielded cable, where the shield is grounded a t 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.

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 togeth er, and all RS485 “–” terminals connected together. The COM terminal should be connected to the common wire inside th e shield, when provided. To avoid loop currents, the shield should be grounded at one point only. 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 increase the number of relays on a single channel to more than 32. Star or stub connections should be avoided entirely.

Lightning strikes and ground surge currents can cause large mo mentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communi cation 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.

ENSURE THE DUST COVERS ARE INSTALLED WHEN THE FIBER IS NOT IN USE. DIRTY OR SCRATCHED

CAUTION

The fiber optic communication ports allow for fast and efficient communications between relays at 10Mbps 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, 9N, 9P, and 9R. The 9H, 9K, 9M, and 9R modul es 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 i n 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.

CONNECTORS CAN LEAD TO HIGH LOSSES ON A FIBER LINK. OBSERVING ANY FIBER TRANSMITTER OUTPUT MAY CAUSE INJURY TO THE EYE.

3.3DIRECT INPUT AND OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION

The N60 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 featu re 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 UR 4-Tx to UR1-Rx. A maximum of sixteen (16) UR-series relays can be connected in a single ring

setting is not applicable to this module.

AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end. Connecting the shield to pin X1a or X6a grounds the shield since these pins are internally connected to ground. Thus, if pin X1a or X6a is used, do not ground at the other end. This interface module is protected by surge suppression devices.

Pin nomenclature may differ from one manufacturer to another. Therefore, it is n ot uncommon to see pinouts numbered TxA, TxB, RxA and RxB. In such cases, it can be assumed that “A” is equivalent to “+” and

NOTE

“B” is equivalent to “–”.

b) G.703 SELECT ION SWITCH PROCEDURES

1. Remove the G.703 mo dule (7R or 7S). The ejector/inserter clips located at th e 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 ea ch 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.

Table 3–5: G.703 TIMING SELECTIONS

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 (L SB) necessary for connecting to higher order systems. When N60s 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) conn ections. 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

The switch settings for the internal and loop timing modes are shown below:

842752A1.CDR

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 sou rce is expected to be from the G.703 line sid e of the interface.

Figure 3–33: G.703 MINIMUM REMOTE LOOPBACK MODE

In dual loopback mode, the multiplexers are active and the function s of the circuit are divide d into two with each receiver/ transmitter pair linked together to deconstruct and then reconstruct their re spective 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 sp lit in the communicatio ns 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 three RS422 inter-relay communications modules available: single-channe l RS422 (module 7T), dual-channel RS422 (module 7W), and dual-channel dual-clock RS422 (modul e 7V). The modules can be configured to run at 64 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 two-channel two-clock RS422 interface (module 7V) is inte nded for use with two independent channel banks with two independent clocks.

NOTE

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

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

• Site 2: Termin ate 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.

Figure 3–36: TYPICAL PIN INTERCONNECTION BETWEEN TWO RS422 INTERFACES

b) TWO-CHANNEL APPLICATION VIA MULTIPLEXERS

The RS422 interface may be used for single channel or two channel applic ations over SONET/SDH or multiplexed systems. When used in single-channel applications, the RS422 interface links to highe r 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 th ese connections are follow ed: The send timing outputs from the multiplexer (data module 1), will connect to the clock inputs of the UR–RS422 interface in the u sual fashion. In addition, the send timing outputs of data module 1 will also be paralleled to the terminal timing inputs of data module 2.

3-30 N60 Network Stability and Synchrophasor Measurement System GE Multilin

3 HARDWARE 3.3 DIRECT INPUT AND OUTPUT COMMUNICATIONS

By using this configuration, the timing for both data modules and both UR–RS422 cha nnels 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 in terface is a viable option that does not impose timing restrictions.

Figure 3–37: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the N60 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 dat a 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, th e following figure shows the positive edge of the Tx clock in the center of the Tx data bit.

3.3 DIRECT INPUT AND OUTPUT COMMUNICATIONS 3 HARDWARE

d) RECEIVE TIMING

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

To recover the Rx clock from the data-stream, an integrated DPLL (dig ital 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.

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 may be n ec essary to ensur e that y ou d o not e xceed max imum 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 modul es are either 64 kbps (with n fixed at 1) for 128 kbps (with n fixed at 2). 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:.

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

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 di rectl y to any compliant digital multiplexe r 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 su pports the IEEE C37.94 standard, as shown below.

The UR-series C37.94 communication module has six (6) switches that are used to set the clock configuration. The functions of these control switches is shown below.

42753A1.CDR

GE Multilin N60 Network Stability and Synchrophasor Measurement System 3-33

3.3 DIRECT INPUT AND OUTPUT COMMUNICATIONS 3 HARDWARE

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 selecti on 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 pul led 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. Ta ke 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.

4 HUMAN INTERFACES 4.1 ENERVISTA UR SETUP SOFTWARE INTERFACE

4 HUMAN INTERFACES 4.1ENERVISTA UR SETUP SOFTWARE INTERFACE 4.1.1 INTRODUCTION

The EnerVista UR Setup software provides a graphical user interface (GUI) as one of two human interfaces to a UR device. The alternate human interface is implemented via the device’s faceplate keypad and display (refer to the Faceplate inter- face section in this chapter).

The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and trouble-shoot the operation of relay functions, connected over local or wide area communication networks. It can be used while disconnected (off-line) or connected ( on-line) to a UR device. In off-line mode, settings files can be created for eventual downloading to the device. In on-line mode, you can communicate with the device in real-time.

The EnerVista UR Setup software, provided with every N60 relay, can be run from any computer supporting Microsoft

95, 98, NT, 2000, ME, and XP. This chapter provides a summary of the basic EnerVista UR Setup software interface

dows features. The EnerVista UR Setup Help File provides details for getting started and using the EnerVista UR Setup software interface.

4.1.2 CREATING A SITE LIST

To start using the EnerVista UR Setup software, a site definition and device definition must first be created. See the EnerVista UR Setup Help File or refer to the Connecting EnerVista UR Setup with the N60 section in Cha pter 1 for details.

4.1.3 ENERVISTA UR SETUP OVERVIEW

a) ENGAGING A DEVICE

The EnerVista UR Setup software may be used in on-line mode (relay connected) to directly communicate with the N60 relay. Communicating relays are organized and grouped by communication interfaces and into sites. Sites may contain any number of relays selected from the UR-series of relays.

Win-

b) USING SETTINGS FILES

The EnerVista UR Setup software interface supports three ways of handling changes to relay settings:

• In off-line mode (relay disconnected) to create or edit relay settings files for later download to communicating relays.

• While connected to a communicating relay to directly modify any relay settin gs via relay data view windows, and then save the settings to the relay.

• You can create/edit settings files and then write them to the relay while the interface is connected to the relay.

Settings files are organized on the basis of file names assigned by the user. A settings file contains data pertaining to the following types of relay settings:

• Device definition

• Product setup

• System setup

• FlexLogic™

• Grouped elements

• Control elements

• Inputs/outputs

• Testing

Factory default values are supplied and can be restored after any changes.

c) CREATING AND EDITING FLEXLOGIC™

You can create or edit a FlexLogic™ equation in order to customize the relay . You can subsequently view the automatically generated logic diagram.

4.1 ENERVISTA UR SETUP SOFTWARE INTERFACE 4 HUMAN INTERFACES

d) VIEWING ACTUAL VALUES

You can view real-time relay data such as input/output status and measured parameters.

e) VIEWING TRIGGERED EVENTS

While the interface is in either on-line or off-line mode, you can view and analyze data generated by tri ggered specified parameters, via one of the following:

• Event Recorder facility: The event recorder captures contextual da ta associated with the last 1024 events, listed in chronological order from most recent to oldest.

• Oscillography facility: The oscillography waveform traces and digital states are used to provide a visual display of power system and relay operation data captured during specific triggered events.

f) FILE SUPPORT

• Execution: Any EnerVista UR Setup file which is double clicked or opened will launch the application, or provide focus to the already opened application. If the file was a settings file (has a URS extension) which had been removed from the Settings List tree menu, it will be added back to the Settings List tree menu.

• Drag and Drop: The Site List and Settings List control bar windows are each mutually a drag source and a drop target for device-order-code-compatible files or individual menu items. Also, the Settings List control bar window and any

Windows Explorer directory folder are each mutually a file drag source and drop target. New files which are dropped into the Settings List window are added to the tree which is automatically sorted alphabet-

ically with respect to settings file names. Files or individual menu items which are dropped in the selected device menu in the Site List window will automatically be sent to the on-line communicating device.

g) FIRMWARE UPGRADES

The firmware of a N60 device can be upgraded, locally or remotely, via the EnerVista UR Setup software. The corresponding instructions are provided by the EnerVista UR Setup Help file under the topic “Upgrading Firmware”.

Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (i.e. default values, minimum/maximum values, data type, and item size) may change slightly from version to versio n of firm-

NOTE

ware. The addresses are rearranged when new features are added or existing features are enha nced or modified.

EEPROM DATA ERROR message displayed after upgrading/downgradi ng the firmware is a resettable, self-test

The message intended to inform users that the Modbus addresses have changed with the upgraded firmware. This message does not signal any problems when appearing after firmware upgrades.

4.2 EXTENDED ENERVISTA UR SETUP FEATURES 4 HUMAN INTERFACES

4.2EXTENDED ENERVISTA UR SETUP FEATURES 4.2.1 SETTINGS TEMPLATES

Setting file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An example of this is a substation that has ten similar feeders protected by ten UR-series F60 relays.

In these situations, typically 90% or greater of the settings are identical betwe en all devices. The temp lates feature allows engineers to configure and test these common settings, then lock them so they are not available to users. For example, these locked down settings can be hidden from view for field engineers, allowing them to quickly identify an d concentrate on the specific settings.

The remaining settings (typically 10% or less) can be specified as editable and be made available to field engineers installing the devices. These will be settings such as protection element pickup values and CT and VT ratios.

The settings template mode allows the user to define which setting s will be visible in EnerVista UR Setup. Settings templates can be applied to both settings files (settings file templates) and online devices (online settings templates). The functionality is identical for both purposes.

The settings template feature requires that both the EnerVista UR Setup software and the N60 firmware are at versions 5.40 or higher.

The settings file and corresponding secure FlexLogic™ equations are now locked to the N60 device specified by the serial number.

4.2.3 SETTINGS FILE TRACEABILITY

A traceability feature for settings files allows the user to quickly determine if the settings in a N60 device have been changed since the time of installation from a settings file. When a setti ngs file is transfered to a N60 device, the date, time, and serial number of the N60 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This information can be compared with the N60 actual values at any later date to determine if security has been compromised.

The traceability information is only included in the settin gs file if a complete settings file is either transferred to the N60 device or obtained from the N60 device. Any partial settings transfers by way of drag and drop do not add the traceabili ty information to the settings file.

SETTINGS FILE TRANSFERRED

TO UR-SERIES DEVICE

The serial number and last setting change date are stored in the UR-series device.

The serial number of the UR-series device and the file transfer date are added to the settings file when settings files are transferred to the device.

Compare transfer dates in the settings file and the UR-series device to determine if security has been compromised.
