Siemens 7SJ6236 Protection Relay

Feature & Principle

It is Siemens SIPROTEC 4 series numerical feeder protection relay. It adopts microprocessor technology, integrates phase overcurrent, earth fault, directional overcurrent, breaker failure protection functions. It supports IEC/ANSI inverse time curves, collects voltage and current signals for power measurement, event recording and fault waveform capture. It can communicate with SCADA system, parameter configuration and fault analysis by DIGSI software. This model has been discontinued, used for substation feeder maintenance replacement.
