INTRODUCTION:

Switchgear (and circuit breakers) are critical components in electrical distribution systems and their operation significantly affects the overall operation of the system. This training course will discuss application, installation, maintenance and testing issues relating to medium and high voltage switchgear and circuit breakers.  Low voltage switchgear will also be covered and you will receive a thorough grounding in switchgear theory and standards.

The participant 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 emphasizes medium voltage switchgear which represents most of the switchgear installed on electrical distribution systems. The focus is on air blast, oil, SF6 and vacuum circuit breakers. 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

OBJECTIVES:

 

At the end of the course participants will :

  • Learn the selection of appropriate type and rating of circuit breakers and switchgear
  • Know the fundamentals of operating switchgear
  • Understand switchgear components (CTs, VTs, relays and cable terminations)
  • Know the safe operational policies including safety rules and safety documents
  • Learn the diagnostic tools and test equipment
  • Learn safe maintenance policies including safe working in switch rooms, indoor and outdoor substations
