How to judge the relay protection device

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 associated with. This handbook covers the code of practice in protection circuitry including standard lead and device numbers, mode of connections at terminal strips, colour codes in multicore cables, dos and donts in execution. Also principles of various protective relays and schemes including special protection. Modern networks rely on and utilize relay protection systems in order to maintain a safe electrical environment by continuously monitoring devices for problems and controlling the grid to isolate problematic areas. 15 seconds in its 30+ year life. But failure to operate as intended can result in extensive damage, extended power outages, and loss of life. NETA (InterNational Electrical Testing Association) reports show 12% Failure Rates on Protective Relays Tested.
