High Voltage Switchgears training seminar focuses mainly on the installation, operation and maintenance of high voltage switchgear and equipment, with reference to auxiliary equipment necessary for its operation. High voltage equipment plays an important role in the safe distribution of electrical power. The equipment needs to be operated in a safe manner securing continuity of supply to consumers. Technical aspects of switching devices as well as their maintenance requirements are briefly included in this training seminar in order to understand the risks associated with switchgear operation. Aspects of modern maintenance techniques in asset managements will be covered at the level appropriate for this training course.

Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system.

This training seminar will highlight:

  • The roles of MV and HV switchgears
  • Compression principles of circuit breakers
  • Application and installation of vacuum interrupters
  • Importance of maintenance and testing
  • Protective relays and characteristics


At the end of the training course, you will learn to:

  • Understand the operations and types of TAMCO high voltage switchgears
  • Develop management and implementation of safe work systems
  • Design coordination of maintenance activities and maintaining system safety
  • Apply air and gas insulated switchgear operations and maintenance
  • Explain the various types of protective relays
  • Analyse troubleshooting and repair of high voltage switchgears
