Power Plant Relay Protection Testing Procedure

Power Plant Relay Protection Testing Procedure

One approach to test the total protection system is to use primary injection techniques (see appendix H) that trigger protective relays and lockout relay, trip circuit breakers, and initiate annunciations and indications. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. But failure to operate as intended can result in extensive damage, extended power outages, and loss of life.
