Schneider Electric PowerLogic™ MiCOM P122 Feeder Protection Relay

Schneider Electric PowerLogic™ MiCOM P122 Feeder Protection Relay combines feeder protection with directional fault detection for medium-voltage distribution systems. In many power networks, fault current can flow from multiple sources, making it important to identify not only the fault but also its direction. The MiCOM P122 helps operators achieve better protection coordination by distinguishing between upstream and downstream fault conditions.

The relay continuously monitors feeder currents and responds to overcurrent and earth fault events before they affect wider sections of the network. Directional protection functions improve selectivity and help reduce unnecessary feeder trips, especially in interconnected distribution systems and ring networks.

MiCOM P122 also records operating events and fault data that support maintenance teams during fault analysis and system troubleshooting. Its compact numerical design makes it suitable for installation in substations, switchgear panels, and industrial power distribution systems.
