Training Overview

Training Overview

The Medium Voltage & High Voltage Switchgear Operations & Maintenance training course offered by Coventry Academy provides a comprehensive exploration of current technologies in medium and high voltage switchgear, focusing on their construction and operational characteristics. Emphasis is placed on the operations and maintenance of key electrical power distribution equipment such as transformers, circuit breakers, and gas-insulated switchgears.

A central theme of the course is the evolution of dielectric substances used in these equipments, driven by global efforts to reduce carbon footprints and eliminate global warming potentials. Participants will delve into new dielectric fluids and gases that enhance environmental protection and extend equipment lifecycle, while improving maintenance, safety, security, and reliability. Modern practices such as remote monitoring and condition-based maintenance will be highlighted as crucial for effective management of medium and high voltage switchgears.

Key topics covered in this training include:

  • Understanding the types of medium voltage and high voltage switchgears
  • Principles of operation for medium voltage circuit breakers
  • Exploration of new eco-efficient fluids and gases in switchgear technology
  • Maintenance and testing procedures for switchgears
  • Construction, operation, and maintenance of high voltage transformers, including remote monitoring and dissolved gas analysis

What are the goals?

By the end of this Coventry Academy training course, participants will be able to:

  • Understand the role and importance of switchgears
  • Determine the components and operations of medium voltage and high voltage circuit breakers characteristics
  • Explain the different types of eco efficient substances, fluids and gases and their applications
  • Analyse the effective conditioned based maintenance for switchgears
  • Testing and measuring instruments for safe operation of switchgears
