What do relay protection departments typically do

Relay Protection Engineers design, test, commission, and maintain protective relay systems that safeguard electrical power equipment — transformers, generators, transmission lines, and buses — from faults, overloads, and abnormal operating conditions. They work at utilities, independent power. 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. It functions as a watchdog by constantly surveying multiple system components including voltage, current, frequency, and phase angle.
