Schneider MiCOM P139 Feeder Protection Relay

Feature & Principle

It samples three-phase voltage and current signals in real time. It implements overcurrent, earth fault, voltage protection, breaker failure protection and automatic reclosing logic. It supports configurable protection settings, fault event recording and oscillography. It communicates with SCADA system via Modbus, IEC60870-5-103 or IEC61850, to realize remote monitoring and control of switchgear.
