2.1.1 OVERVIEW
The F60 Feeder Protection System is a microprocessor based relay designed for feeder protection.
Overvoltage and undervoltage protection, overfrequency and underfrequency protection, breaker failure protection, direc-
tional current supervision, fault diagnostics, RTU, and programmable logic functions are provided. This relay also provides
phase, neutral, ground and negative sequence, instantaneous and time overcurrent protection. The time overcurrent func-
tion provides multiple curve shapes or FlexCurves™ for optimum co-ordination. Automatic reclosing, synchrocheck, and
line fault locator features are also provided. When equipped with a type 8Z CT/VT module, an element for detecting high
impedance faults is provided.
Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total
waveform RMS magnitude, or as fundamental frequency only RMS magnitude and angle (phasor).
Diagnostic features include a sequence of records capable of storing 1024 time-tagged events. 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 deter-
mined throughout the system. Events can also be programmed (via FlexLogic™ equations) to trigger oscillography data
capture which may be set to record the measured parameters before and after the event for viewing on a personal com-
puter (PC). 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 pro-
gramming of settings and the monitoring of actual values. The RS232 port has a fixed baud rate of 19.2 kbps. 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-T Ethernet interface provides fast, reliable communications in noisy environments. The
Ethernet port supports IEC 61850, IEC 61850-90-5, Modbus/TCP, and TFTP protocols, PTP (according to IEEE Std. 1588-
2008 or IEC 61588), and allows access to the relay via any standard web browser (F60 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.
Settings and actual values can be accessed from the front panel or EnerVista software.
The F60 IEDs use flash memory technology which allows field upgrading as new features are added. The following single
line diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.
