At its core, an overcurrent relay operates on a very simple concept: detect excessive current, then trip fast and isolate the fault. When current surpasses the relay's pickup setting, an internal mechanism triggers the circuit breaker. IEEE/IAS/I&CPSD Protection & Coordination WG Chair Jacobs Canada, Calgary, AB rasheek. com IEEE Southern Alberta Section PES/IAS Joint Chapter Technical Seminar - November 2016 Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: Protective relays and devices. Relay protection against high current was the earliest relay protection mechanism to develop. From this basic method, the graded overcurrent relay protection system, a discriminative short circuit protection, has been formulated. Types of over current relay. It is really current monitoring relay. Overcurrent Relay Definition: An overcurrent relay is a protective device that operates solely based on current without the need for a voltage coil. These relays are known for their speedy operation during a fault and are hence used widely in high-voltage applications. Let's know in. The Art and Science of Protective Relaying, by C. Mason, John Wiley and Sons, 1956. Evaluation of Distribution System Relaying Methods, by A. McConnell, Presented at the Pennsylvania Elec-tric Association, May 16-17, 1957.
