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. The primary protection scheme ensures fast and selective clearing of any circuit fault within the boundaries of the circuit element, that the.

This video explains how to connect a thermal overload relay with self-hold (latching) contact to protect motors from overload and overheating. 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. We'll show you how to pick up the device, predicting the maturing of emergencies exceeding the maximum allowable current indicators.
