What are the classifications of relay protection systems
Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function (time-based, current, voltage). Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. There are many types of protective relays, and each one is designed for a specific type of protection. Common types include overcurrent relay, differential relay, distance relay, earth fault relay, and under/over voltage relay. It initiates the operation of circuit breakers to isolate the affected section. The relay can be made to respond to either a single quantity or a combination of two or all input quantities.
