Course Description

For various reasons, electrical system grounding and bonding procedures are not very well understood. This seminar provides up-to-date theory, practice and knowledge necessary for design, construction, safety, operations and management of electrical facilities. The seminar offers a comprehensive coverage of grounding and bonding procedures, electrical code requirements, substation and safety grounding, sensitive electronic equipment and lightning protection. Practical case studies are used to reinforce knowledge of the grounding and bonding principles studied during the seminar.

Each participant will receive a set of notes that will serve as information and reference.
