Relay protection tiered coordination
Relay coordination refers to setting protective devices so that the relay closest to the fault operates first, while upstream relays act as backups. Relay coordination is one of the most critical aspects of electrical power system protection. In an electric power system, overcurrent or excess current is a situation where a larger than intended electric current exists through a conductor, leading to excessive generation of heat, and the risk of. 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.
