Home / Retesting of Power System Relay Protection
A comprehensive testing program should simulate fault and normal operating conditions of the relay. Acceptance testing, commissioning, and startup will include control power tests, current transformer and potential transformer tests, and any other device testing . The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. This piece outlines some of the most effective relay protection testing techniques with which every technician can benefit from operational insights learned and best practices applied. NETA (InterNational Electrical Testing Association) reports show 12% Failure Rates on Protective Relays Tested.
