Relay protection signal transmission path
Distance Relay: Operates based on impedance, commonly used in transmission line protection. Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: 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. Many important issues, such as coordination of settings, operating times, characteristics of. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. 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.
