PROTECTIVE RELAY WORKING TYPES AND APPLICATIONS

Three Types of Relay Protection

Three Types of Relay Protection

A protective relay is an electronic device used in power systems to monitor and analyze electrical parameters, such as current, voltage, and frequency, and to take action to protect electrical equipment and ensure system stability. Directional relays are advanced protective devices capable of distinguishing the direction of current flow in an electrical system. If the difference exceeds the pickup value of the relay, it operates to trip the breakers to isolate the element.
