Schneider MiCOM P922G PowerLogic Interconnection Protection Relay
Schneider MiCOM P922G PowerLogic Interconnection Protection Relay is designed to protect distributed generation systems operating in parallel with the utility grid. It is suitable for renewable energy plants, industrial power generation systems, cogeneration facilities, and other applications where reliable grid interconnection protection is essential.
The relay continuously monitors electrical parameters and responds quickly to abnormal operating conditions to help protect generators, transformers, and connected equipment. It supports stable synchronization, secure grid connection, and dependable disconnection whenever network conditions fall outside permissible limits.
MiCOM P922G combines multiple protection, control, monitoring, and measurement functions in a single unit, reducing the need for separate protection devices. Its configurable logic allows engineers to adapt the relay to different grid codes and project requirements, making it suitable for both new installations and retrofit projects. With support for standard industrial communication protocols, the relay integrates easily with SCADA and substation automation systems.
