What does relay protection action mean
A protective relay operates by continuously monitoring electrical parameters, detecting abnormalities, making decisions, and triggering circuit breakers to isolate faulty sections. 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. Electromechanical protective relays at a hydroelectric generating plant. The relays are in round glass cases. In this blog, we'll discuss the essentials of protective relaying, exploring how it helps maintain system.
