Training course overview

This Medium Voltage & High Voltage Switchgear Operations & Maintenance training course will open a new window to current technologies related to the medium voltage and high voltage switchgear construction and characteristics. It will focus mainly only the operations and maintenance of electrical power distribution equipment namely the transformers, circuit breakers and gas insulated switchgears.

The common denominator for these equipment’s is the dielectric substance used. In view of the world’s reduce carbon footprint and elimination of global warming potentials new dielectric fluids and gases have emerged and have crept into the electrical power installations. This Medium Voltage & High Voltage Switchgear Operations & Maintenance training course will discuss the new innovations which not only protect the environment but also extends the life cycle costs, maintenance, safety, security and reliability of the equipment. Remote monitoring and conditioned based maintenance will be the mainstay of all modern medium voltage and high voltage switchgears.

This Coventry Academy training course will feature:

  • Understanding the types of medium voltage and high voltage switchgears
  • Operation principle of medium voltage circuit breakers
  • Identification of the various new fluids and gases used in an eco-efficient switchgear
  • Maintenance of testing of 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

Who is this training course for?

This Coventry Academy training course will benefit all levels of professional in an electrical installation. It will enable them to understand operations and maintenance of medium and high voltage circuit breakers and switchgears. This training course will greatly benefit:

  • Electricians
  • Electrical supervisors
  • Plant electricians
  • Operations & maintenance engineers, supervisors & technicians
  • Maintenance technicians

How will this training course be presented?

This Coventry Academy training course will utilise a variety of proven adult training techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes presentation and discussion of latest videos and technologies on medium and high voltage switchgears.

Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss with the Presenter specific issues and, if possible, find appropriate solutions. Specific goals of each participant will be discussed to ensure that their needs are fulfilled whenever practicable.
