What are the four types of relay protection devices

This article covers various types of protective relays, such as overcurrent, directional, and differential relays, highlighting their operating characteristics and applications in electrical systems. Different Types of Protective Relays What is a Protective Relay?Protective Relay Definition: A protective relay is an automatic device that senses abnormal conditions in electrical circuits and triggers actions to isolate faults. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. A relay isolates or alters an electric circuit. Relay classification depends on what they're used for.
