Schneider Electric PowerLogic™ MiCOM P925 Voltage and Frequency Management Relay

Schneider Electric PowerLogic™ MiCOM P925 Voltage and Frequency Management Relay is built for power systems that need stable voltage and frequency control together with automation and load management functions. It is used in applications where the relay has to do more than simply detect abnormal conditions. In many networks, the real challenge is keeping the system stable during disturbances and restoring normal operation in a controlled way once the event has passed.

The MiCOM P925 is suited for those kinds of duties. It combines voltage and frequency supervision with control logic, load shedding support and restoration functions in one relay platform. This makes it useful in utility substations, industrial plants and captive power systems where operators need a coordinated response to falling frequency, voltage problems or sudden changes in system demand.

Another practical benefit of the relay is its ability to support system recovery after a disturbance. Loads that have been disconnected as part of a protection or management scheme can be restored in a controlled sequence once the network stabilises. That helps reduce downtime and avoids bringing the system back too quickly after a fault or major frequency event.
