About the course

Participants will cover the maintenance and testing requirements for common substation devices, including power transformers, oil, air and vacuum circuit breakers, switchgear, ground grid systems, batteries, chargers and insulating liquids. This course focuses on what to do, when to do it and how to interpret the results from testing and maintenance.

Course Objectives

Upon the completion of this course, each participants will be able to:-

  • Learn the damage electricity can cause to the human body and understand the basic principles of safety in normal and abnormal conditions
  • Learn to recognize and avoid unsafe work areas
  • Learn correct approach distances
  • Have a better understanding of proper voltage rated tools and the use of proper personal protection equipment
  • Learn how to provide assistance in determining severity of potential exposure to high voltage arc flash hazards, planning safe work practices and selecting proper personal protective equipment.
