Protective relays are used across feeders, transformers, generators, motors, buses, and transmission lines to isolate faults, maintain system stability, and minimize equipment damage . They act as decision-making devices, while circuit breakers or other interrupting devices perform the actual disconnection of the faulted section. In summary, relay protection encompasses a variety of mechanical, electronic, and digital devices, each tailored to detect specific abnormal conditions and ensure the safe and reliable operation of electrical power systems .
