Addendum

ADDENDUM

This addendum contains information that relates to the D30 Line Distance Protection System, version 6.0x. This adden­dum lists a number of information items that appear in the instruction manual GEK-113599 (revision X1) but are not
included in the current D30 operations.

The following functions and items are not yet available with the current version of the D30 relay:

• Signal sources SRC 3 to SRC 6.

Version 4.0x and higher releases of the D30 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 8L, 8M.

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

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

-- 8M Sensitive ground 4CT/4VT 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

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.

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

1

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.

1

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

1

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 D30 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 D30 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 D30 rear communications port. The converter termi­nals (+, –, GND) are connected to the D30 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 , 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.

1.5.7 COMMISSIONING

The D30 requires a minimum amount of maintenance when it is commissioned into service. Since the D30 is a micropro­cessor-based relay, its characteristics do not change over time. As such, no further functional tests are required.

Furthermore, the D30 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 D30 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 D30 Line Distance Protection System is a microprocessor-based relay intended for use on transmission lines of any
voltage level, without, with, and in the vicinity of series compensation, in three-pole tripping applications. The primary func­tion of the relay consists of three phase and ground distance zones of protection, either mho or quadrilateral as per user
selection. The distance elements are optimized to provide good measurement accuracy with a fast operating time, even
when used with capacitive voltage transformers, and can be supervised by detection of power swings. The relay also pro­vides directional ground overcurrent elements, which are commonly used as part of an overall line protection system.

D30 phase distance zones can be configured to work with voltages and currents fed from VTs and CTs located indepen­dently from one another on either side of a three-phase power transformer. The relay compensates accordingly to preserve
reach and correct target information regardless of the location and type of fault. This feature allows backup protection appli­cations for generators and power transformers.

A close-into-fault (or switch-on-to-fault) function is performed by the line pickup element. Out-of-step tripping, three-pole
autoreclosing, synchrocheck, fault location, and many other functions are also available. In addition, overcurrent and
undervoltage protection, fault diagnostics, power metering, and RTU functions are provided. The D30 provides phase, neu­tral, and ground time overcurrent protection. The time overcurrent functions can be programmed with multiple curve shapes
or FlexCurve™ for optimum coordination.

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).

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 used for time-tagging can be synchronized via IRIG-B 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 (D30 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 D30 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.

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.

where OPB = optical power budget, P
and P

= receiver sensitivity.

R

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:

ETHERNET (10/100 MB TWISTED PAIR)

Modes: 10 MB, 10/100 MB (auto-detect)

Connector: RJ45

SNTP clock synchronization error: <10 ms (typical)

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 m glass fiber optic cable is approxi-
mately 2.8 dB per km. In our example, this would result in the fol­lowing maximum fiber length:

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

The D30 Line Distance 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 D30.

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. Modules with current
input provide automatic shorting of external CT circuits.

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 D30 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

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

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.

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 D30 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 D30 has a redundant option in which two D30 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.

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.

The exact placement of a zero-sequence core balance CT to detect ground fault current is shown below. Twisted-pair
cabling on the zero-sequence CT is recommended.

3.2.5 PROCESS BUS MODULES

The D30 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 D30 by reducing the number of individual copper terminations.

• Integrates seamlessly with existing D30 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 D30 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

3

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.

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 # 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.

NOTE

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 , 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

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.

3

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.

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.

3

Figure 3–20: 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.

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 3–21: 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.

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 trans­ducer 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.

3.2.8 RS232 FACEPLATE PORT

A 9-pin RS232C serial port is located on the D30 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.

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,

Figure 3–24: CPU MODULE COMMUNICATIONS WIRING

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 D30 COM terminal (#3); others function cor­rectly only if the common wire is connected to the D30 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.

ENSURE THE DUST COVERS ARE INSTALLED WHEN THE FIBER IS NOT IN USE. DIRTY OR SCRATCHED
CONNECTORS CAN LEAD TO HIGH LOSSES ON A FIBER LINK.

OBSERVING ANY FIBER TRANSMITTER OUTPUT MAY CAUSE INJURY TO THE EYE.

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, 9N, 9P, and 9R. The 9H, 9K, 9M, and 9R 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 3–26: 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 3–27: 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 D30 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 sixteen (16) UR-series relays can be connected in a single ring

3

Figure 3–28: DIRECT INPUT AND OUTPUT SINGLE CHANNEL CONNECTION

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.

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

a) DESCRIPTION

The following figure shows the 64K ITU G.703 co-directional interface configuration.

The G.703 module is fixed at 64 kbps. The

SETTINGS  PRODUCT SETUP  DIRECT I/O  DIRECT I/O DATA RATE

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.

3

Figure 3–33: G.703 INTERFACE CONFIGURATION

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 3–34: 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.

GE Multilin D30 Line Distance Protection System 3-29

3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

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.

Figure 3–35: G.703 TIMING SELECTION SWITCH SETTING

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 (LSB) necessary for connecting
to higher order systems. When D30s 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

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 3–36: 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.

3

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 3–40: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the D30 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 may be necessary to ensure that you do not exceed maximum

3

optical input power to the receiver.

3.3.8 IEEE C37.94 INTERFACE

The UR-series IEEE C37.94 communication modules (modules types 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) 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 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 directly to any compliant digital multiplexer that supports
the IEEE C37.94 standard as shown below.

3

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.

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.

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.

GE Multilin D30 Line Distance Protection System 3-35

3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

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 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).

3

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 m 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.

3

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

The UR-series C37.94SM communication module has six (6) 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.

GE Multilin D30 Line Distance Protection System 3-37

3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

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

1. Remove the C37.94SM module (modules 2A or 2B):

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).

3

5. Replace the top cover and the cover screw.

6. Re-insert the C37.94SM 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.

The type 2S and 2T embedded managed switch modules are supported by UR-series relays containing type 9S CPU mod­ules with revisions 5.5x and higher. The modules communicate to the D30 through an internal Ethernet port (referred to as
the UR port or port 7) and provide an additional six external Ethernet ports: two 10/100Base-T ports and four multimode ST
100Base-FX ports.

The Ethernet switch module should be powered up before or at the same time as the D30. Otherwise, the switch
module will not be detected on power up and the

EQUIPMENT MISMATCH: ORDERCODE XXX self-test warning will be

issued.
