Grounding System Design and Testing of Electrical Equipment Course

Course Overview:

This course covers grounding and bonding systems according to the Canadian Electrical Code and other normative documents in depth.

Rounding aspects as well as system grounding techniques and bonding connections will be studied to facilitate electrical safety and efficacious design. 

Topics include deep discussions on grounding system designs, their maintenance, applications which include neutral grounding resistors and test procedures. Safety aspects such as arc flash and ground fault relations, touch and step voltages, and substation grounding design are thoroughly covered. 

The audience for this training are engineers, technologists, consultants, and contractors and after completing the training, the attendees have knowledge on practical approaches to meeting compliance requirements, reliability, and safety in grounding system projects.
