How to Protect Transmission Lines?
This post outlines major ways for protecting transmission lines from faults and disruptions, such as the use of protective relays, fault detection
Home / What is a transmission line in relay protection
Transmission line protection is the coordinated use of protective relays, instrument transformers, circuit breakers, communication channels, and backup logic to detect faults on high-voltage lines and isolate the affected section. Transmission lines act like the arteries in the human circulatory system, moving electrical power from were it is produced by generators to where it is consumed at load centers. Abstract: Information on the concepts of protection of ac transmission lines is presented in this guide.
