What are the types of circuit relay protection
There are many types of protective relays, and each one is designed for a specific type of protection. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. A protective relay is an intelligent electrical device designed to detect faults in power systems and initiate corrective actions such as tripping a circuit breaker. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. There are different types of relays available and each type is used based on the requirement. These relays sense abnormal conditions like overcurrent, under-voltage, or short circuits and send a signal to circuit breakers to open the circuit.
