2.1.1 Overview

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. A faceplate RS232 port 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.
