Grounding System Design and Testing of Electrical Equipment Course
Introduction:
Grounding of any power system is a must for safety and compliance with the Canadian Electrical Code. This course covers concepts of system grounding and equipment grounding; safety grounding of equipment in substations; IEEE 80 method of safety grounding design; applicable standards and grounding codes; installation, testing, and maintenance of grounding; and also discusses electrical system anomalies. Concepts are illustrated through case studies and hands-on exercises.
