Utility Relay Protection - Advanced - This 12-hour live online instructor-led training course is a must have for all electric utility transmission and distribution engineers who enter into the Protection & Control field and electrical technicians.

The main objective of this course is to identify, discuss and develop solutions to common utility protection issues. This popular course gives students a comprehensive understanding of the principles of electric utility protection relaying and applications.

Electric utility protective relays are deployed throughout the T&D power system for the purpose of sensing abnormal electrical events and operating conditions They isolate, working in tandem with circuit breakers, any abnormal conditions that resulting from environmental effects, physical accidents, equipment breakdown or operational failure which is caused by human error.

A reliable, selective and high-speed isolation and protection system is necessary to prevent damage to vital and expensive utility asset equipment, reduce the risk of serious danger to humans and to maintain power system stability and acceptable power quality.

These stringent requirements, with high potential consequences, make it imperative that utility relay protection systems are designed and maintained to perform their functions with a very high degree of dependability and security.
