Market Definition
A protective relay is a power system component that senses abnormalities or faults in the power system and initiates the control circuit operation. Major power system components such as transmission lines, feeders, busbars, transformers, motors, generators, and capacitor banks are capital-intensive assets that need to be protected in case of faults. Protective relays serve this purpose by continuously monitoring system health and by initiating switchgear operation to disconnect the faulty sections of the power network.
