What does a relay protection branch protect
Protective relays are used in industrial power generation and supply systems to open and isolate branch circuits in the case of excessive current. They are activated by means which are not dependent on a continual AC supply. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. Relion protection and control relays for several application reduce complexity. In electrical engineering, a protective relay is a relay device. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. A protective relay definition is; a switchgear device used to detect faults & begin the circuit breaker operation to separate the faulty element of the system.
