Relay protection should refrain from operating rather than operate erroneously
Unlike the rotating machines or other equipment, the protective relays remain standstill and without operation until a fault develops. determinations made by planning coordinators under Reliability. 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. Although failure of a protective relay system may have severe local or regional impacts, most protective relay systems are not required to operate to prove they are in working order. This document provides recommendations, background and philosophy on relay protection that is not available in M07.
