Dl relay protection inspection cycle
Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring. They were talking about doing away with full testing on microprocessor based relays after initial commissioning, relying on the relay's self-test features and metering checks on the relay, and circuit function checks for the equipment being protected. These guidelines should be strictly adhered to during maintenance activities. The maintenance activities for protection relays can be categorized into three main areas:. The purpose of this paper is to provide recommendations for testing SEL relays and guidance for developing a test program.
