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.

C70 Capacitor Bank Protection and Control System
Chapter 2: Product description
Product description
This chapter outlines the product, order codes, and specifications.
2.1 Product description
The C70 Capacitor Bank Protection and Control System is part of the Universal Relay (UR) series of products. It is a
microprocessor-based relay for protection and control of small, medium, and large three-phase capacitor banks. The relay
can be ordered with up to three current transformer/voltage transformer (CT/VT) modules, allowing for flexible application
in variety of bank configurations.
The key protection functions cover grounded and ungrounded, single and parallel banks. Sensitive protection functions
support compensation for both external (system) unbalance and inherent unbalance of the capacitor bank itself. Both
voltage and current-based balance protection functions are available. Algorithms are developed to automatically select
compensation settings after repairs or other alternations of the bank.
The relay supports a variety of bank configurations through flexible configurations of its AC inputs, installed voltage and
current transformers, and resulting protection techniques.
The relay incorporates an automatic voltage regulator (AVR) responding to voltage, reactive power, or power factor. A
separate timer function initiates controls on a pre-defined time/date basis. These on-off type controls are meant to
automatically close or open the associated breaker. A supervisory function is provided to program the local/remote, auto/
manual functionality, temporary inhibit closing after tripping, and other auxiliary functions, such as operation counters.
A capacitor control element provides remote/local and auto/manual control regulation, trip/close interlocking, and seal-in.
A user-programmable time delay inhibits closing until after the bank discharges itself to a safe level.
The relay can also equipped with a serial 64/128 kbps direct input/output module for fast and reliable peer-to-peer
communication with other UR-series devices.
The C70 metering functions include true root mean square (RMS) and phasors for currents and voltages, current and
voltage harmonics and total harmonic distortion (THD), symmetrical components, frequency, power, power factor.
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
with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time
Protocol (PTP). 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.

PRODUCT DESCRIPTION CHAPTER 2: PRODUCT DESCRIPTION
Several options are available for communication. A faceplate RS232 port can be used to connect to a computer to
program settings and monitor 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. 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 (C70 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 can be accessed from the front panel or EnerVista software.
The C70 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
C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 2-3
2
SECURITY CHAPTER 2: PRODUCT DESCRIPTION
• 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
users can enter commands and/or change settings.
The C70 supports password entry from a local or remote connection. Local access is defined as any access to settings or
commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote
access is defined as any access to settings or commands via any rear communications port. This includes both Ethernet
and RS485 connections. Any changes to the local or remote passwords enables this functionality.
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 C70, the remote password must be used. If the
connection is to the RS232 port of the faceplate, the local password applies.
Password access events are logged in the Event Recorder.
2.2.0.3 CyberSentry security
CyberSentry embedded security is available using a software option (Level 1) that provide advanced security services.
When the 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
device 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 away from common operator functions, or engineering type access,
all of which are defined by separate roles (see figure) so that access of UR devices by multiple personnel within a
substation is allowed.

CyberSentry user authentication
The following types of authentication are supported by CyberSentry to access the UR device:
2-6 C70 CAPACITOR BANK PROTECTION AND CONTROL 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 only.
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 PT 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.
2-14 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL
CHAPTER 2: PRODUCT DESCRIPTION SIGNAL PROCESSING
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.
Figure 2-3: UR signal processing
2
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 A/D 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.
C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 2-15
SPECIFICATIONS CHAPTER 2: PRODUCT DESCRIPTION
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
2
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 the 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 transformers 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 and
others. 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 C.37.118-2011 and
C.37.118.1a-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
are also available via IEC 61850-90-5 protocol.
Contact inputs threshold is settable in the firmware with 17, 33, 84, 166 VDC 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 ms 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 Data Logger, allowing much slower rates extended over
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.

3.2.3 Rear terminal layout
Do not touch any rear terminals while the relay is energized, else death or serious injury can
result from electrical shock.
The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated
transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur.
The relay follows a convention with respect to 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 marker 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 a period longer than the specified minute.
3.3.3 Control power
Control power supplied to the relay must be connected to the matching power supply range of the
relay. If voltage is applied to the wrong terminals, damage can occur.
The C70, 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 C70 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 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 de-energizes.
For high-reliability systems, the C70 has a redundant option in which two C70 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.

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 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 channels are labeled 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 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 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.
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.

3.3.5 Process bus modules
The C70 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.

CHAPTER 3: INSTALLATION WIRING
3.3.6 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 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 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. If the inputs must be isolated per row, then two inputs per common return are selected (4D module).
The tables and diagrams on the following pages 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.
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.

WIRING CHAPTER 3: INSTALLATION
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.
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).

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.
Figure 3-16: Dry and wet contact input connections

Where a tilde “~” symbol appears, substitute the slot position of the module.
There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend
using an external DC supply.
Contacts outputs of protective relays, auxiliary switches from breakers, disconnectors and other devices, are generally
connected to contacts inputs of protective relays. In some situations, the contact outputs of some protective relays can
have high impedance connected across it. When such a contact output is connected across a C70 contact input, it can
spuriously operate the C70 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 C70 input and the debounce time setting in the C70
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 C70 input.
The following figure shows a typical DC circuit, with battery ground detection, of contact input . The contact output has
apparent impedance across it (represented by R1).
C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 3-21

WIRING CHAPTER 3: INSTALLATION
Figure 3-17: Typical contact input DC circuit
The presence of the impedance path (R1) across the contact output allows the stray (distributed) capacitance to charge as
shown, thus developing a voltage across the contact input enough to momentarily operate the input while the
capacitance discharges in the presence of DC ground on the positive terminal of the battery.
The duration of the discharge depends on the value of the distributed capacitance, the initial voltage of the distributed
capacitance, and the input impedance of the contact input. If the duration is greater than the debounce time setting, then
the contact input operates.
The application example that follows describes how to mitigate this problem by connecting a resistor across the contact
input, as shown in the next figure, or by adjusting the debounce time setting to a value greater than the discharge time to
prevent spurious operation of the contact input only if the voltage (with output open) across the contact input due to trickle
current is less than the threshold voltage. This operation of contact inputs also can be prevented by using the Auto-Burnish
contact inputs.
Figure 3-18: 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.
3-22 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION WIRING
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).
Therefore, discharge time constant (τ) =50 kΩ *0.1 μF = 5 ms.
Discharge period t is calculated from the following equation:
Vthreshold = (Vbatt - VInitial) *e^ (-t/τ)
84 = -149 *e^ (t/0.005) Eq. 3-1
T = -0.005 * ln (84/149) = 0.0029 s
Therefore, in this example the contact inputs operate.
To prevent this operation, the debounce time must be increased to 4 ms (set debounce time as per the following table) or
insert a resistor less than or equal to "R" as calculated later.
Table 3-5: Typical debounce time setting
Stray capacitance (μF) Battery voltage (V) Debounce time (ms)

0.2 130 6
0.05 250 3
0.1 250 6
0.2 250 11
3
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 Open) 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 closed, 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.

3.3.6.2 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 has a five-second delay after a contact input changes state.
Figure 3-19: 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
auto-burnishing 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. 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 3-20: Auto-burnish DIP switches
3-24 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION WIRING
The auto-burnish circuitry has an internal fuse for safety purposes. During regular maintenance, check the auto-burnish
functionality using an oscilloscope.
3.3.6.3 Use of contact inputs with active impedance
In case of external devices that are susceptible to parasitic capacitance of long cable runs affected by switching surges
from external circuits, that can cause inadvertent activation of contact inputs with the external contact open, GE
recommends using the Digital I/O module with active impedance circuit.
Active impedance contact input can tolerate external capacitance of up to 0.2 µF, without entering the ON state for more
than 2 ms. The contact input debounce time can be set above 2 ms to prevent the transient ON state from being internally
used by the relay logic.
The figure shows the active impedance contact input V-I characteristic.
Figure 3-21: Active impedance contact input V-I characteristic
3
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. The contact input is in the ON (operated state) if the input voltage is to the
right of the 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.

3.3.7 Transducer inputs and outputs
Transducer input modules can 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.
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 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.
Where a tilde “~” symbol appears, substitute the slot position of the module.

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 C70 COM terminal (#3); others function correctly only if the
common wire is connected to the C70 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.

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
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. Using the IRIG-B input, the C70 operates an internal oscillator with 1 µs
resolution and accuracy. The IRIG time code formats are serial, pulse width-modulated codes that can be either DC level
shifted or amplitude modulated (AM). 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.

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.

DIRECT INPUT AND OUTPUT COMMUNICATIONS CHAPTER 3: INSTALLATION
Figure 3-28: Direct input and output single-channel connection
IRC modules with protocol C37.94 and G.703 are designed for back-to-back communication connections, so the ring
configuration shown in the previous figure does not apply. To establish inter-relay communication in more than two URs,
you need to have two channel IRC module and enable DIRECT I/O CHANNEL CROSSOVER function in all relays, as shown in
the next figure. This configuration can be expanded to 16 URs, and this configuration does not provide redundancy ring
since both channels are made into single ring by the channel crossover function. As per the figure Typical Pin
Interconnection between Two G.703 Interfaces later in this chapter, the clock is supplied typically by multiplexer (MUX) and
all URs are in Loop Timing Mode. If there is no MUX, then UR1 and UR3 can be in Internal Timing Mode and UR2 and UR4
can be in Loop Timing Mode. That is, connected channels must have opposite timing modes.
Figure 3-29: Ring configuration for C37.94 module (concept also applies to G.703)
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.

3.4.3.2 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.

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).

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 3-37: 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.

3.4.4 RS422 interface
3.4.4.1 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 20-24 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.
Figure 3-39: RS422 interface connections
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 3-40: Typical pin interconnect between two RS422 interfaces
3.4.4.2 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 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) connects to the clock inputs of the UR RS422 interface in the usual way. In
3-38 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION DIRECT INPUT AND OUTPUT COMMUNICATIONS
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 are 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 3-41: Timing configuration for RS422 two-channel, three-terminal application
3
Data module 1 provides timing to the C70 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.
3.4.4.3 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.
C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 3-39
3
DIRECT INPUT AND OUTPUT COMMUNICATIONS CHAPTER 3: INSTALLATION
Figure 3-42: Clock and data transitions
3.4.4.4 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.
3.4.5 IEEE C37.94 interface
The UR-series IEEE C37.94 communication modules (module types 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. 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 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 communication module can be connected directly to any compliant digital multiplexer that supports
the IEEE C37.94 standard. The figure shows the concept.
3-40 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION DIRECT INPUT AND OUTPUT COMMUNICATIONS
Figure 3-43: IEEE C37.94 connection to compliant digital multiplexer
The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a noncompliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard. The
following figure shows the concept.
Figure 3-44: 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 the module and is to be used on all ends of C70
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.
Figure 3-45: Switches
3
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 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.
2. Simultaneously pull the ejector/inserter clips located at the top and bottom of each module in order to release the
module for removal.
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 (see description earlier).
6. Replace the top cover and the cover screw.
7. 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 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.
