FOR FURTHER ASSISTANCE CHAPTER 1: INTRODUCTION

Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety
cautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.

Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to
attempting work on the device.

Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that
current transformer secondary circuits are shorted out before making or removing any connection to the current
transformer (CT) input terminals of the device.

For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such
equipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated,
unless this is required by the test procedure and is specified by appropriate utility/plant procedure.

When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching
apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are working
on or around this primary equipment to prevent any inadvertent command from this device.

Use an external disconnect to isolate the mains voltage supply.
Personal safety can be affected if the product is physically modified by the end user. Modifications to the product

outside of recommended wiring configuration, hardware, or programming boundaries is not recommended end-use
practice. Product disassembly and repairs are not permitted. All service needs to be conducted by the factory.

LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class 1M. Class 1M
devices are considered safe to the unaided eye. Do not view directly with optical instruments.

This product is rated to Class A emissions levels and is to be used in Utility, Substation Industrial
environments. Not to be used near electronic devices rated for Class B levels.

Chapter 2: Product description

Product description

This chapter outlines the product, order codes, and specifications.

2.1 Product description

The C60 Breaker Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay
for breaker monitoring, control, and protection in electrical substations and industrial automation.

Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total
waveform root mean square (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 and oscillography capable of
storing up to 64 records with programmable trigger, content, and sampling rate. The internal clock used for time-tagging
can be synchronized with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using
the Precision Time Protocol (PTP). The internal clock used for time-tagging can be synchronized with an IRIG-B signal or via
the SNTP 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 that can be
set to record the measured parameters before and after the event for viewing on a computer. These tools significantly
reduce troubleshooting time and simplify report generation in the event of a system fault.

Several options are available for communication. An RS232 port (USB port with the graphical front panel) can be used to
connect to a computer for the programming of settings and the monitoring of actual values. The rear RS485 port allows
independent access by operating and engineering staff. It can be connected to system computers with baud rates up to

115.2 kbps. All serial ports use the Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485
interface. IEC 60870-5-103, DNP, and Modbus cannot be enabled simultaneously on this interface. Also only one of the
DNP, IEC 60870-5-103, and IEC 60870-5-104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103
protocol is chosen, the RS485 port has a fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The
100Base-FX or 100Base-TX Ethernet interface provides fast, reliable communications in noisy environments. The Ethernet
port supports IEC 61850, Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access
to the relay via any standard web browser (C60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet
port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when
purchased as an option.

Secure Routable GOOSE (R-GOOSE) is supported with software options.
Settings and actual values are accessible from the front panel or EnerVista software.
The C60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are

upgradable.

2.2 Security

The following security features are available:

• Password security — Basic security present by default

• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The
feature is present by default in the EnerVista software.

• CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.

2.2.0.1 EnerVista security

The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a
substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security
management system is disabled by default to allow the administrator direct access to the EnerVista software after
installation. It is recommended that security be enabled before placing the device in service.

Basic password or enhanced CyberSentry security applies, depending on purchase.

2.2.0.2 Password security

Password security is a basic security feature present by default.
Two levels of password security are provided: command and setting. Use of a password for each level controls whether all

users can enter commands and/or change settings.
Two types of connection security are provided: password entry from local or remote connection. Local access is defined as

any access to settings or commands via the front panel interface. This includes both keypad entry and the through a front
panel port. Remote access is defined as any access to settings or commands via any rear communications port. This
includes both Ethernet and RS485 connections. These two settings are on by default and apply to all users.

When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the C60, the remote password is used. If the
connection is to a front panel port, the local password applies. (These two local and remote password settings are not
shown the figure.)

Password access events are logged in the Event Recorder.

2.2.0.3 CyberSentry security

CyberSentry security is available using software options that provide advanced security services. When an option is
purchased, the basic password security is disabled automatically.

CyberSentry provides security through the following features:

• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards­based strong cryptography for authentication and credential protection

• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device
operations and configurations based on specific roles and individual user accounts configured on the AAA server (that
is, Administrator, Supervisor, Engineer, Operator, Observer roles)

• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring

• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National
Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems

CyberSentry user roles

CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in role.

Example: Administrative functions can be segmented from common operator functions, or engineering type access, all of
which are defined by separate roles so that access of UR devices by multiple personnel within a substation is allowed.

One role of one type is allowed to be logged in at a time. For example, one Operator can be logged in but not a second
Operator at the same time. This prevents subsets of settings from being changed at the same time.

CyberSentry user authentication

The following types of authentication are supported by CyberSentry to access the UR device:

2-6 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL

CHAPTER 2: PRODUCT DESCRIPTION ORDER CODES

• Device Authentication (local UR device authenticates)

• Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local

UR device or the RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the

"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator, or Administrator and
Supervisor when Device Authentication is disabled) as login names and the associated passwords are stored on the UR
device. As such, when using the local accounts, access is not user-attributable.

In cases where user-attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication.

When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.

No password or security information is displayed in plain text by the EnerVista software or UR device, nor is such
information ever transmitted without cryptographic protection.

CyberSentry server authentication

The UR has been designed to direct automatically the authentication requests based on user names. In this respect, local
account names on the UR are considered as reserved and not used on a RADIUS server.

The UR detects automatically whether an authentication request is to be handled remotely or locally. As there are five local
accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR forwards
automatically the request to a RADIUS server when one is provided.

If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this
situation, use local UR accounts to gain access to the UR system.

2.4 Signal processing

2.4.1 UR signal processing

The UR series relays are microprocessor-based protective relays that are designed to measure power system conditions
directly via CT and VT inputs and via other sources of information, such as analog inputs, communications inputs, and
contact inputs. The following figure shows the overall signal processing in URs.

An analog low pass anti-aliasing filter with a 3 dB corner frequency is set at 2.4 kHz and is used for current and voltage
analog filtering as well as signal conditioning. The same filtering is applied for phase, ground currents, phase-to-phase
(when applicable), and auxiliary voltages. The 2.4 kHz cut-off frequency applies to both 50 Hz and 60 Hz applications and
fixed in the hardware, and thus is not dependent on the system nominal frequency setting.

C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL 2-17

SIGNAL PROCESSING CHAPTER 2: PRODUCT DESCRIPTION

Figure 2-4: UR signal processing

The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz systems.
The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking
system.

The analog/digital converter has the following ranges of AC signals:
Voltages:

Eq. 2-1

Currents:

Eq. 2-2

Current harmonics are estimated based on raw samples with the use of the full-cycle Fourier filter. Harmonics 2nd through
25th are estimated.

2-18 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL

CHAPTER 2: PRODUCT DESCRIPTION SPECIFICATIONS

True RMS value for the current is calculated on a per-phase basis. The true RMS can be used for demand recording or as an
input signal to Time Overcurrent function, if the latter is intended for thermal protection. The true RMS is calculated as per
the widely accepted definition:

Eq. 2-3

RMS values include harmonics, inter-harmonics, DC components, and so on, along with fundamental frequency values.
The true RMS value reflects thermal effects of the current and is used for the thermal related monitoring and protection
functions.

Protection and control functions respond to phasors of the fundamental and/or harmonic frequency components
(magnitudes and angles), with an exception for some functions that have an option for RMS or fundamental
measurements, or some function responding to RMS only. This type of response is explained typically in each element's
section in this instruction manual.

Currents are pre-filtered using a Finite Impulse Response (FIR) digital filter. The filter is designed to reject DC components
and low-frequency distortions, without amplifying high-frequency noise. This filter is referred to as a modified MIMIC filter,
which provides excellent filtering and overall balance between speed and accuracy of filtering. The filter is cascaded with
the full-cycle Fourier filter for the current phasor estimation.

Voltages are pre-filtered using a patented Finite Impulse Response (FIR) digital filter. The filter has been optimized to reject
voltage-transformer-specific distortions, such as Capacitive Voltage Transformer (CVT) noise and high-frequency
oscillatory components. The filter is cascaded with the half-cycle Fourier filter for the voltage phasor estimation.

The URs measure power system frequency using the Clarke transformation by estimating the period of the waveform from
two consecutive zero-crossings in the same direction (negative-to-positive). Voltage or current samples are pre-filtered
using a Finite Impulse Response (FIR) digital filter to remove high frequency noise contained in the signal. The period is
used after several security conditions are met, such as true RMS signal must be above 6% nominal for a certain time. If
these security conditions are not met, the last valid measurement is used for a specific time after which the UR reverts to
nominal system frequency.

Synchrophasors are calculated using a patented convolution integral algorithm. This algorithm allows use of the same
time-stamped samples, which are used for protection and taken at the same sampling frequency. This allows URs to use
one sampling clock for both protection algorithms and synchrophasors.

Synchrophasors on firmware versions 7.23 and up have been tested and certified to meet IEEE C37.118-2011 and
C37.118.1a-2014 standards for both metering and protection classes with outputs available up to 60 synchrophasors per
second for the metering class and 120 synchrophasors per second for the protection class. Synchrophasors measurement
is also available via IEC 61850-90-5 protocol.

The contact inputs threshold is settable in the firmware with 17, 33, 84, 166 V DC settings available. Inputs are scanned
every 0.5 ms and can be conditioned for the critical applications, using debounce time timer, settable from 0.0 to 16.0 ms.
Contact inputs with auto-burnishing are available as well, when external contacts are exposed to the contamination in a
harsh industrial environment.

All measured values are available in the UR metering section on the front panel and via communications protocols.
Measured analog values and binary signals can be captured in COMTRADE format with sampling rates from 8 to 64
samples per power cycle. Analog values can be captured with the Data Logger, allowing much slower rates extended over
a long period of time.

Other advanced UR order code options are available to support IEC 61850 Ed2.0 (including fast GOOSE, MMS server, 61850
services, ICD/CID/IID files, and so on), IEEE 1588 (IEEE C37.238 power profile) based time synchronization, CyberSentry
(advanced cyber security), the Parallel Redundancy Protocol (PRP), IEC 60870-5-103, and so on.

3.2 Panel cutouts

This section does not apply to the HardFiber Brick; see its instruction manual.
Install the relay in an indoor environment within the environmental specifications. The relay complies with Pollution

Category II, which means installation in an office, laboratory, or testing environment.

3.2.1 Horizontal units

The C60 is available as a 19-inch rack horizontal mount unit with a removable front panel. The front panel is specified as
enhanced, standard, or graphical at the time of ordering. The enhanced and graphical front panels contain additional
user-programmable pushbuttons and LED indicators.

The modular design allows the relay to be upgraded and repaired by qualified service personnel. The front panel is hinged
to allow access to the modules. The front panel is itself removable to allow mounting on doors with limited rear depth and
for upgrading.

In November 2017, GE began transitioning to a new enhanced horizontal front panel. This panel can be identified by the
use of a screw instead of a knob to close the panel. It can conform to an IP54 rating with the IP54 mounting collar
purchased separately. The IP54 mounting collar can be used in panel-mount installations, not 19-inch rack-mount
installations. The IP54 mounting collar cannot be used with old enhanced front panels.

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

The relay must be mounted such that the front panel sits semi-flush with the panel or switchgear door, allowing the
operator access to the keypad and the front communications port .

3.2.3 Rear terminal layout

3

Do not touch any rear terminals while the relay is energized, else death or serious injury can
result from electrical shock.

Small form-factor pluggable ports (SFPs) are pluggable transceivers. They transmit, receive, and
convert electrical signals to optical signals and vice-versa. They are inserted into the Ethernet ports
on the CPU module. A photo in the Maintenance chapter shows this plug-in device. Do not use non­validated transceivers or install validated transceivers in the wrong Ethernet slot, else damage can
occur.

The relay follows a convention for terminal number assignments, which are three characters long and assigned 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), indicated by an arrow on the terminal block. The figure shows 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 longer than the specified minute.

3.3.3 Control power

Power supplied to the relay must be connected to the matching power supply range of the relay. If
incorrect voltage is applied or voltage is applied to the wrong terminals, damage can occur.

The C60, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well­known to deteriorate over time if voltage is not applied periodically. Deterioration can be avoided by
powering up the relay at least once a year.

The power supply module can be ordered for two possible voltage ranges, and the C60 can be ordered with or without a
redundant power supply module option. Each range has a dedicated input connection for proper operation. The ranges
are as follows (see the Specifications section of chapter 2 for 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 is energized once control power is applied
and the relay has successfully booted up with no critical self-test failures. If ongoing self-test diagnostic checks detect a
critical failure (see the Self-Test Errors section in chapter 7) or control power is lost, the relay de-energizes.

To connect power to the relay, 14 gauge stranded wire with disconnect devices is recommended. Connect all wires to the
relay before turning on power.

C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL 3-15

3

WIRING CHAPTER 3: INSTALLATION

For high-reliability systems, the C60 has a redundant option in which two C60 power supplies are placed in parallel on the
bus. If one of the power supplies becomes faulted, the second power supply assumes the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate that it is functional. The critical fail
relay of the module also indicates a faulted power supply.

An LED on the front of the control power module shows the status of the power supply, as outlined in the table.

Table 3-2: Power supply LED on module

LED indication Power supply

Continuous on OK
On/off cycling Failure
Off Failure or no power

Figure 3-15: Control power connection

When using a C60 with a HardFiber system, before powering off the C60, save data in the compact flash memory
using Commands > Relay Maintenance > Save Non-Volatile Data. When not saved or the relay loses power, up to
the last two minutes of data is not saved to the compact flash memory.

When using an SH power supply module, after disconnecting power and powering up again, some measured values
displayed can change from that last displayed. This is because there is not enough time for the compact flash to store
data. Upon power up the last stored value displays.

3.3.4 CT/VT modules

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

A CT/VT module can have current or 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 labelled 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 channels 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).

3-16 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL

CHAPTER 3: INSTALLATION WIRING

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

To connect to the module, size 12 American Wire Gauge (AWG) is used commonly; the maximum size is 10 AWG.
CT/VT modules can 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 can be used.

CT/VT modules with a sensitive ground input are also available. The ground CT input of the sensitive ground modules is 10
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.

These modules have enhanced diagnostics that 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 as follows. Twisted-pair

cabling on the zero-sequence CT is recommended.

Figure 3-16: Zero-sequence core balance CT installation

The phase voltage channels are used for most metering and protection purposes. The auxiliary voltage channel is used as
input for the synchrocheck and volts-per-hertz features, which are optional features for some UR models.

WIRING CHAPTER 3: INSTALLATION

Figure 3-17: CT/VT module wiring

3.3.5 Process bus modules

The C60 can be ordered with a process bus interface module. The module interfaces with the HardFiber Process Bus
System, or HardFiber Brick, allowing bidirectional IEC 61850 fiber-optic communications with up to eight HardFiber Bricks.
The HardFiber system integrates seamlessly with the existing UR-series applications, including protection functions,
FlexLogic, metering, and communications.

This process bus system offers the following benefits:

• Reduces labor associated with design, installation, and testing of protection and control applications using the UR by
reducing the number of individual copper terminations

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

• Communicates using open standard IEC 61850 messaging

For details on the HardFiber system, see its Instruction Manual.

3.3.6 Contact inputs and outputs

Nearly all contact input/output modules have 24 terminal connections. The connections are arranged typically as three
terminals per row, with eight rows in total. A given row of three terminals can 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 input/output modules have three versions of grouping: four
inputs per common return, five inputs per common return on a high-density module, and two inputs per common return.
When a contact input/output module is ordered, four inputs per common is used. If the inputs must be isolated per row,
then two inputs per common return are selected (4D module). If the space limitation in the relay requires use of a high­density input module (6W), five inputs share one common return and the module has six banks of inputs.

The tables and diagrams that follow illustrate the module types (6A and so on) and contact arrangements that can 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.

3-18 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL

CHAPTER 3: INSTALLATION WIRING

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 there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the
current monitor is set to “On = 1” when the current flowing through the closed contact 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. 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.

Block diagrams are shown as follows 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. Form-A contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity
shown in the figure is required for solid-state contact output connection.

Figure 3-18: Form-A and solid-state contact outputs with voltage and current monitoring

3

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

OP # VOFF, and CONT OP # ION) that 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.

See 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.

Consider relay contacts unsafe to touch when the unit is energized. Death or serious injury can
result from touching live relay contacts.

WIRING CHAPTER 3: INSTALLATION

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 can
continue to read the form-A contact as being closed after it has closed and subsequently opened, when measured
as an impedance.

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

Where a tilde “~” symbol appears, substitute the slot position of the module. Where 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, give the
FlexLogic operand driving the contact output 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).

For high-density input/output modules 6W and 6X, use the following guidelines to connect:

• 12 to 24 AWG (3.3 mm

• 16 to 24 AWG (1.31 mm

• Minimum suggested temperature rating for the conductors is 75°C

• Wire type: copper

For proper functionality, observe the polarity shown in the figures for all contact input and output
connections.

3.3.6.1 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 that 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 flows 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 detects 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.

WIRING CHAPTER 3: INSTALLATION

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.

3.3.6.2 General application considerations

Contacts outputs of protective relays, auxiliary contacts from breakers, disconnectors and other devices are connected
generally to contacts inputs of protective relays. In some situations, the contact outputs of some protective relays can
have high impedance connected across it. When such a contact output is connected across a C60 contact input, it can
spuriously operate the C60 input even when the output is open, if there is a substantial distributed capacitance
(represented by C1) present in the wiring between the output and the C60 input, and the debounce time setting in the C60
relay is low enough. This false assertion of the contact input, when there is inadvertent ground present at the DC positive
terminal, can be prevented by inserting a resistor across the C60 input.

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

Figure 3-23: Typical contact input DC circuit

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

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

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

CHAPTER 3: INSTALLATION WIRING

Figure 3-24: Contact input connected to a contact output with resistor (R2) across the input

Application example

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

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

3

Table 3-4: Discharge period

Battery voltage (V) Input impedance (kΩ)

130 50
250 97

Debounce time setting = 2 ms
Assume a stray capacitance of 0.1 μF.
Assume an initial voltage across the stray capacitance "Vinitial" = 19 V (Vthreshold - 65 V), where Vthreshold = 84 V. The

initial voltage Vinitial depends on values of impedance of R1 and contact inputs when the contact input is OFF (non­activated state).

Therefore, discharge time constant (τ) =50 kΩ *0.1 μF = 5 ms.
Discharge period t is calculated from the following equation:

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

84 = -149 *e^ (t/0.005) Eq. 3-1

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

Therefore, in this example the contact inputs operate.
To prevent this operation, the debounce time must be increased to 4 ms (set debounce time as per the following table) or

insert a resistor less than or equal to "R" as calculated later.

Stray capacitance (μF) Battery voltage (V) Debounce time (ms)

0.1 250 6 *

0.2 250 11

* Default debounce time on contact inputs is 6 ms.

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

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

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

R = (Vthreshold / 3) / (2 mA) Eq. 3-2

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

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

PR = 1.3 * (Vbatt) ^2 / R Watts Eq. 3-3

4. Applying the following equation to our example:

R = 84 V / 3 * (1 / 2 mA) = 14 kΩ

PR = 1.57 Watts Eq. 3-4

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

Vresistor = 2 mA * 14 Kohm = 28 V

Vresistor < contact input threshold (84 V) Eq. 3-5

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

3.3.6.3 Use of contact inputs with auto-burnishing

The contact inputs sense a change of 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 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 has a five-second delay after a contact input changes state.

Figure 3-25: Current through contact inputs with auto-burnishing

3-28 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL

CHAPTER 3: INSTALLATION WIRING

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with
auto-burnishing allow currents up to 50 to 70 mA at the first instance when the change of state is sensed. Then, within 25
to 50 ms, this current is slowly reduced to 3 mA as indicated. 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 (see 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 3-26: Auto-burnish DIP switches

3

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

3.3.6.4 Use of contact inputs with active impedance

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

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

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

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

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

3.3.7 Transducer inputs and outputs

Transducer input modules receive input signals from external DCmA output transducers (DCmA In) or resistance
temperature detectors (RTDs). Hardware and software are 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.

Each transducer input/output module has 24 terminal connections. These connections are arranged as three terminals
per row over eight rows. A given row can 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 following figure illustrates the
transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay.

WIRING CHAPTER 3: INSTALLATION

3.3.9.2 RS485 port

RS485 data transmission and reception are accomplished over a single twisted-pair wire with transmit and receive data
alternating over the same two wires. Through the use of the port, continuous monitoring and control from a remote
computer, SCADA system, or Power Line Carrier (PLC) is possible.

To minimize errors from noise, the use of shielded twisted-pair wire is recommended. Correct polarity must 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 C60 COM terminal (#3); others function correctly only if the
common wire is connected to the C60 COM terminal, but insulated from the shield.

To avoid loop currents, ground the shield 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 needs to 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. Avoid star or stub
connections 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 provided internally at both communication ports. An
isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum
reliability, ensure that all equipment has similar transient protection devices installed.

Terminate both ends of the RS485 circuit with an impedance as shown in the figure.

3.3.9.3 100Base-FX fiber optic ports

The fiber-optic communication ports allow for fast and efficient communications between relays at 100 Mbps. Optical
fiber can be connected to the relay supporting a wavelength of 1310 nm in multimode.

CHAPTER 3: INSTALLATION WIRING

Ensure that 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.

3.3.10 IRIG-B

There is a round IRIG-B connector at the back of the CPU module, marked "IN". Use is optional.
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The

IRIG-B code allows time accuracies of up to 100 ns. The GE MultiSync 100 1588 GPS Clock as well as third-party equipment
are available for generating the IRIG-B signal. This equipment can use a global positioning system (GPS) satellite system to
obtain the time reference so that devices at different geographic locations can be synchronized. The IRIG time code
formats are serial, pulse width-modulated codes that can be either DC level shifted or amplitude modulated (AM). Using
IRIG-B input, the C60 operates an internal oscillator with 1 µs resolution and accuracy.

DIRECT INPUT AND OUTPUT COMMUNICATIONS CHAPTER 3: INSTALLATION

3.4 Direct input and output communications

3.4.1 Description

The direct inputs and outputs feature makes use of the type 7 series of communications modules and allows direct
messaging between UR devices. The communications modules are outlined in the table later in this section.

The communications channels are normally connected in a ring configuration, as shown in the following figure. 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
illustrates a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to
UR4-Rx, and UR4-Tx to UR1-Rx. A maximum of 16 URs can be connected in a single ring.

3

Figure 3-34: Direct input and output single-channel connection

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

DIRECT I/O CHANNEL CROSSOVER setting

The interconnection for dual-channel type 7 communications modules is shown as follows. 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.

3.4.4 G.703 interface

3.4.4.1 Description

G.703 is an International Telecommunications Union (ITU) standard for the transmission of data and voice signals. Modules
7R (one channel) and 7S (two channels) apply.

The following figure shows the 64K ITU G.703 co-directional interface configuration. This is module 7S.
The G.703 module is fixed at 64 kbps. The

applicable to this module.
AWG 24 twisted shielded pair wiring 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 connected internally to ground. Thus, if
pin X1a or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is
protected by surge suppression devices.

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 Layout section earlier in this chapter. All pin interconnections are to be
maintained for a connection to a multiplexer.

Pin nomenclature differs from one manufacturer to another. It is not uncommon to see pinouts numbered TxA, TxB,
RxA, and RxB. In such cases, assume that “A” is equivalent to “+” and “B” is equivalent to “–.”

3.4.4.2 G.703 selection switch procedures

1. With the power to the relay off, remove the G.703 module (7R or 7S) as follows. Record the original location of the
module to help ensure that the same or replacement module is inserted into the correct slot.

2. Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release
the module for removal. (For more information on accessing modules, see the Maintenance chapter.)

3. Remove the module cover screw.

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

5. Set the timing selection switches (channels 1 and 2) to the required timing modes.

6. Replace the top cover and the cover screw.

7. 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 bottom of each module must be in the disengaged position as the
module is inserted smoothly 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 is inserted fully.

Switches Function

S1 OFF → octet timing disabled

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

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

3.4.4.3 G.703 octet timing

If octet timing is enabled (ON), this 8 kHz signal is asserted during the violation of bit 8 (LSB) necessary for connecting to
higher order systems. When C60s are connected back-to-back, octet timing is disabled (OFF).

3.4.4.4 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, set the G.703 timing selection to internal

timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set 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, set the G.703 timing

selection to 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).

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

3.4.4.5 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 that 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 3-45: 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.

3.4.5 RS422 interface

3.4.5.1 Description

There are two RS422 inter-relay communications modules available: single-channel (module 7T) and dual-channel (module
7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 20 to 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 connected internally 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
Match the clock terminating impedance with 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 3-48: Typical pin interconnect between two RS422 interfaces

3.4.5.2 Two-channel application via multiplexers

The RS422 interface can 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 way, 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 functions correctly when
the following connections are observed and your data module has a terminal timing feature. Terminal timing is a common
feature in 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) connects to the clock inputs of the UR RS422 interface in the usual way. In

C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL 3-43

DIRECT INPUT AND OUTPUT COMMUNICATIONS CHAPTER 3: INSTALLATION

addition, the send timing outputs of data module 1 are also 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 is derived from a single clock
source. As a result, data sampling for both of the UR RS422 channels is synchronized via the send timing leads on data
module 1, shown as follows. If the terminal timing feature is not available or this type of connection is not wanted, the
G.703 interface is a viable option that does not impose timing restrictions.

Figure 3-49: Timing configuration for RS422 two-channel, three-terminal application

Data module 1 provides timing to the C60 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 because they vary by manufacturer.

3.4.5.3 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.

CHAPTER 3: INSTALLATION DIRECT INPUT AND OUTPUT COMMUNICATIONS

Figure 3-50: Clock and data transitions

3.4.5.4 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 digital phase lock loop (DPLL) 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 serial communication controller (SCC) receive clock.

3.4.6 RS422 and fiber interface

The following figure shows the combined RS422 plus fiberoptic interface configuration at 64 K 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 20 to 24 twisted shielded pair wiring is recommended for external RS422 connections. Ground the shield only at one
end. For the direct fiber channel, address power budget issues properly.

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

and channel 2 via direct fiber. AWG 24 twisted shielded pair wiring is recommended for external G.703 connections
connecting the shield to pin 1a at one end only. For the direct fiber channel, address power budget issues properly. See
previous sections for details on the G.703 and fiber interfaces.

3.4.8 IEEE C37.94 interface

IEEE C37.94 is a standard interface between teleprotection equipment and digital multiplexers.
The UR-series IEEE C37.94 modules (module types 2G, 2H, 2I, 2J, 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. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer
and a teleprotection device. Data speed is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n
= 1, 2,…, 12. The UR-series C37.94 communication modules are either 64 kbps (with n fixed at 1) or 128 kbps (with n fixed at

2). The frame is a valid International Telecommunications Union (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 × 128 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 nm or 62.5 μm core diameter optical fiber

• Fiber-optic mode — multimode

• Fiber-optic cable length — up to 2 km

• Fiber-optic connector — type ST

• Wavelength — 820 ±40 nm

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

The UR-series C37.94 module can be connected directly to any compliant digital multiplexer that supports the IEEE C37.94
standard. The figure shows the concept.

following figure shows the concept.

Figure 3-54: IEEE C37.94 connection to non-compliant digital multiplexer

In 2008, GE Grid Solutions released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault
location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this
feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60
and higher, the module can be identified with "Rev D" printed on it and is to be used on all ends of C60 communication for
two and three terminal applications. Failure to use it at all ends results in intermittent communication alarms. For
customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.

The UR-series C37.94 communication module has six switches to set the clock configuration. The following figure shows
the functions of these control switches.

For the internal timing mode, the system clock is generated internally. Therefore, set the timing switch selection to 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, set the timing selection to
loop timing mode for connections to higher order systems.

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

1. With power to the relay off, remove the IEEE C37.94 module (type 2G, 2H, 2I, 2J, 76, or 77 module) as follows. Record

the original location of the module to help ensure that the same or replacement module is inserted into the correct
slot.

3.4.9 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 multi­mode 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 ITU-recommended G.704 pattern from the standpoint of framing and data rate. The
frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:

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

• Fiber-optic cable type — 9/125 μm core diameter optical fiber

• Fiber-optic mode — Single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver

• Fiber-optic cable length — Up to 11.4 km

• Fiber-optic connector — Type ST

• Wavelength — 1300 ±40 nm

• Connection — As per all fiber-optic connections, a Tx-to-Rx connection is required
