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.
