Power Protection
Overview
This unit aims to provide the concepts and principles of electrical protection techniques in today's power systems. The unit also covers different types of protection systems, application of protection to generators, motors, transformers, and electrical system communications for protection application in of modern electrical energy system. Students will learn to analyse and detect different types of faults in power systems.
