IPR-A2
Phase Over-Current & Ground Fault Relay
Current Protection Relay IPR-A is designed to protect medium voltage lines against over-current and short circuit scenarios present in line fault or ground fault even under disturbances. Currents are measured throughout current transformers (CT) from each line. The information is internally processed in order to take the current protection actions defined under ANSI, IAC or IEC standard.
Features
CT primary ratio selectable in 5 A steps (10 A to 6000 A)
Line and ground RMS currents measurement
1 trip relay and 2 programmable auxiliary relay
Control power drop or internal fault relay
Digital inputs: 1 breaker status - 3 programmable
Touchpad programming
Breaker operation and trip failure
