Current protection relay IPR-D

for generatorsDIN railpanel-mount

Ground Protection Relay Ground Protection Relay (IPR-D) has been designed to measure the ground RMS current under normal conditions or under disturbances. The current signals are sensed throughout a current transformer (CT). This information is internally processed by the microprocessor in order to take the current protection actions defined under ANSI, IAC or IEC standard. Applications Primary and backup protection for utility feeder, power plants and industrial distribution systems Protection and Functionality (50G/50N) Instantaneous ground overcurrent (51G/51N) Inverse time ground overcurrent ANSI, IAC or IEC/BS142 curves included: moderately inverse normal inverse very inverse extremely inverse definite time Overload alarm pickup level Communication Communication port: (1) RS232 and (2) RS485 Remote programming of the setpoints Communication Protocol: Modbus RTU
