Operating Principles and Relay Construction: Electromagnetic relays, thermal relays, static relays, microprocessor based protective relaysOperating Principles and Relay Construction: Electromagnetic relays, thermal relays, static relays, microprocessor based protective relaysTo introduce all kinds of circuit breakers and relays for protection of Generators, Transformers and feeder bus bars from Over voltages and other hazards. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to.
