What are the relay protection units
A relay protection system typically consists of three components: the measurement unit, the logic unit, and the execution unit. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. Relion protection and control relays for several application reduce complexity. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. Microprocessor-based solid-state digital protection relays now emulate the original devices, as well as providing types of protection and supervision impractical with electromechanical relays.
