Switchgears (and circuit breakers) are obviously critical components in electrical distribution systems and their operation significantly affects the overall operation of the system. Switchgears construction, installation, maintenance and testing is an issue related to electricity and the high and medium voltage circuit breakers. There will also be coverage of low voltage switchgear.

You will receive a thorough grounding in switchgear theory and standards. You will gain a solid understanding of the issues associated with the proper application, installation and maintenance of these critical items of equipment with an overriding emphasis on safety.

This Course covers important topics related switchgear construction, switchgear operation and maintenance, switchgear equipments testing, control circuits construction and installation, and accident prevention in operation and maintenance of power system equipments.

Case studies covering the main manufacturer’s equipment will illustrate the important practical principles. Other power system protection components will be discussed as well to ensure that switchgear is understood in the correct context.
