2 PRODUCT DESCRIPTION 2.1 F650 OVERVIEW
F650 is a protection, control, monitoring, metering and registering unit, suitable for many different applications, such as
main protection for distribution feeders and transmission lines, as well as backup protection for transformers, busbars,
capacitor banks, etc.
Overvoltage and undervoltage protection, overfrequency and underfrequency protection, breaker failure protection,
directional current supervision fault diagnostics and programmable logic functions are provided.
This relay also provides phase, neutral, ground and sensitive ground, instantaneous and time overcurrent protection. The 2
time overcurrent function provides multiple curve shapes or FlexCurves™ for optimum co-ordination. Automatic reclosing,
synchrocheck, and line fault locator features are also provided.
Voltage, current, power, and energy metering is built into the relay as a standard feature. Current parameters are available
as true RMS magnitude, or as RMS magnitude of fundamental frequency and angle (phasor).
Diagnostic features include a sequence of records. The internal clock used for time-tagging can be synchronized with an
IRIG-B signal or via SNTP, DNP or Modbus protocol over the Ethernet port. Besides this, starting from the version 7.00
IEEE1588 time protocol is also available. The precise time stamping allows the sequence of events to be determined
throughout the system. Oscillography data capture 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 simplify report
generation in the event of a system fault.
A faceplate RS232 or USB port may be used to connect to a PC for the programming of settings and the monitoring of
actual values.
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 RTU protocol. Optional communications modules include a 100BaseFX
®
Ethernet interface which can be used to provide fast, reliable communications in noisy environments.
Another option provides two 100BaseFX fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus /
®
TCP, DNP 3.0 and TFTP protocols, and allows access to the relay via any standard web browser. The IEC 60870-5-104
protocol is supported on the Ethernet port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) and
High-availability Seamless Redundancy (HSR) of IEC 62439-3 (clause 4 (PRP) and clause 5 (HSR)) for firmware version
7.00 and so on.
Rear port COM1 could be set to support IEC60870-5-103 protocol
The F650 IEDs use flash memory technology which allows field upgrading as new features are added:
