2 PRODUCT DESCRIPTION 2.1INTRODUCTION
The F60 Feeder Management Relay 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 or via the SNTP protocol 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 which may be set to record the measured parameters before
and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and sim-
plify report generation in the event of a system fault.
A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual val-
ues. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and
engineering staff. All serial ports use the Modbus
with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules
include a 10BaseF Ethernet interface which can be used to provide fast, reliable communications in noisy environments.
Another option provides two 10BaseF fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus
TCP, and TFTP protocols, 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. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.
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.
