Schneider Electric PowerLogic™ P7 Bay Control Unit

The Schneider Electric PowerLogic™ P7 Bay Control Unit is an intelligent bay management device designed for monitoring, control and automation of medium and high-voltage substations. It combines bay control, supervision, interlocking, measurements and communication functions in a single platform, helping utilities and industries simplify substation operation while improving system reliability.

The unit provides centralized control of circuit breakers, disconnectors and earthing switches, allowing operators to monitor equipment status and perform switching operations safely. Built-in programmable logic supports customised control schemes and reduces the need for additional hardware within the substation.

Developed on the PowerLogic P7 platform, the Bay Control Unit supports IEC 61850 communication, redundant Ethernet networks and advanced cybersecurity. It integrates easily with SCADA, energy management and substation automation systems, making it suitable for both new installations and modernization projects.
