Electrical Maintenance Training

Electrical Maintenance Training

Our Basic Electrical Maintenance Training course will discuss application, installation, electrical maintenance and testing issues related to Low Medium and High Voltage Electric Circuit Breakers, Switchgear and Electrical Power Transformers.

Our Electrical Maintenance training course will provide students with a solid understanding of theory and standards. The course will also make students aware of issues concerning the proper application, installation and maintenance of these types of equipment with a strong emphasis on safety. Our electrical maintenance training course will cover a wide range of material starting from the basics and moving on to more complex issues. This course provides an overview of electric power system design and theory, focusing on the types of equipment used most commonly in the Utility, Industrial, Commercial and Institutional applications. Basic Circuit Breaker and Transformer construction, electrical safety, and common maintenance techniques are major components of this course.



This course is designed to enable students to:

  • Understand Switchgear, Circuit Breaker and Transformer Design
  • Work safely around substation equipment.
  • Understand the operating principles associated with the covered equipment.
  • Understand typically used protection and control systems.
  • Understand the interrelationships of electrical tests.
  • Understand the interpretation of test results.


WHO should attend

This course is recommended for skilled trades, supervisors and anyone involved in the electrical maintenance and operation of Circuit Breakers, Power Transformers, Cable Testing and Motor Testing and Maintenance.
