What are the different types of relay protection for power lines
There are many types of protective relays, and each one is designed for a specific type of protection. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. Line protection relays play a crucial role in safeguarding electrical power transmission and distribution systems. They act as the first line of defense by detecting and isolating faults or abnormal conditions on power lines to prevent damage to equipment and ensure the safe and reliable operation. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. A substation can employ many relaying systems to protect the equipment associated with the station.
