Schneider Electric PowerLogic™ P7 Multi-Bay Feeder Protection

The Schneider Electric PowerLogic™ P7 Multi-Bay Feeder Protection is designed for substations where multiple feeder bays need reliable protection, control and monitoring from a single intelligent platform. It combines advanced feeder protection with bay control, automation and communication functions, helping utilities and industrial facilities simplify substation design while improving operational efficiency.

The system protects multiple incoming and outgoing feeders against short circuits, earth faults, overloads and other abnormal operating conditions. By bringing several feeder protection functions together, it reduces panel space, minimizes wiring complexity and simplifies engineering without compromising protection performance.

Built on the PowerLogic P7 platform, it supports modern digital substations with IEC 61850 communication, redundant Ethernet networks and advanced cybersecurity features. Its flexible architecture makes it suitable for both new substations and upgrade projects where reliability and scalability are important.
