F50/51, F50N/51N, F67N, F27/59, 59Uo, F74, F86, I²t
- Lagged,
- Appropriate for protection of Energy Distribution Systems that is earth over resistance or balanced over neutral,
- It can make control of VAr and has all electrical measurements such as V, I, PF, Hz, W, VAr, VA, Wh, VArh,
- It can show the position of circuit breaker on the its LCD screen,
- It can make on-off locally or remotely,
- Serial communication of RS232 in protocol of Modbus-RTU and RS485 in protocol of IEC 870-5-103/ Modbus-RTU,
- Current-time curves are programmable,
- It can allow for oscilloscopic failure and trip analysis,
- It can make time-labeled 100 event records,
- 14 digital inputs and 10 relay outputs,
- Microprocessor Reclosing Feeder Management Relay
Real-time measurements of the primary values ??of the inputs can be transferred through a serial communication interface program of MSCom. Also, it is available on relay screen continuously.
The control of circuit breaker can be made with relay keypad, it can be also made through the serial communication with MSCom interface program.
Settings, events and oscilloscopic records are saved in long-time memory (E²PROM).
The relay is equipped with auto-tuned multi-voltage power supply card. There are two types as below:
Type1: 24 110 V AC 20% - 24 125 V DC 20%
Type2: 80 220 V AC 20% - 90 250 V DC 20%
As well as automatic test and function of power failure, there are test and diagnostic comparison programs which provide the following features:
-Diagnostic and functional test which controls the content of memory and programs as long as the supply voltage.
- Dynamic function test every 15 minutes for normal operation
- Complete test which can activate the output relays, in case of opening or not opening, via keyboard or communication port
Giving the warning in case of R-5 relay is not energized and an error message appears on the screen when any tested internal failure occurs.
Relay has three different applications: panel installation, surface installation, 19" slide installation
