Introduction and applications of switchgear


Switchgear (and circuit breakers) are critical components in electrical distribution systems and their operation significantly affects the overall performance of the system. This course discusses the application, installation, maintenance, and testing issues related to medium and high voltage switchgear circuit breakers. 

Low voltage switchgear is covered including its theory and standards. You will gain a solid understanding of the issues associated with the use of these critical items with an emphasis on safety. The focus is on medium voltage (referred today as high voltage) switchgear which represents most of the switchgear installed on electrical distribution systems, particularly air blast, oil, SF6 and vacuum circuit breakers.

Case studies covering the main manufacturers’ equipment illustrate the important practical principles. Other power system protection components are covered as well to ensure that switchgear is understood in the correct context. 

The course will develop and enhance your understanding of what is involved in the maintenance of these essential components of power systems, through the tips and tricks learnt and developed by some of the world's best electrical engineers.
