An online intensive professional development training course on

Safe Operations &
Maintenance of Circuit
& Switchgears

Importance of Efficient Operations of the Various Types of Circuit Breakers and Switchgears Incorporating Modern Testing Instruments

Why Choose this Online Training Course?

This highly informative online training course emphasises on the new technologies of medium and high voltage circuit breakers. One of the salient innovations is the elimination of sulphur hexafluoride gas to the new green gas for grid, in line with the world’s effort to reduce the carbon footprint. It will also provide delegates a solid understanding on the safe use of circuit breakers, switchgears and associated equipment that requires correct initial selection, operation and maintenance. New vacuum circuit breaker technologies will be discussed to enhance the safety and secured operation of the electrical installation.

On completion, delegates will be equipped or will have enhanced skills to ensure that circuit breakers and switchgear are installed, operated safely and maintained in a fashion that ensures safe and stable and continuous operation. Delegates will be exposed to recognize faults and ensure the underlying causes are identified to reduce possible further failures. State of the art testing instruments are discussed focusing on circuit breakers and motors.

This AZTech online training course will feature:

  • Understanding the types and functions of circuit breakers
  • Operation principle of medium and high voltage circuit breakers
  • Identification of testing equipment and instruments
  • Interpretation of single line drawings
  • Troubleshooting and maintenance of switchgears

What are the Goals?

By the end of this AZTech online training course, participants will be able to:

  • Understand the various types and operations of circuit breakers
  • Determine the components and operations switchgears
  • Explain the different types of testing instruments
  • Analyse the common faults in an electrical installation
  • Inculcate greater confidence, working safely on circuit breakers and switchgears

Who is this Online Training Course for?
