Fault Modes of Relay Protection Equipment

Relay failure types can be broadly classified into failures from wear, typified by worn out contacts, and deterioration failures, such as layer shorts in coil windings. 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. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
