Description

The course presents the repair and operations, testing and maintenance of different H.V. power component such as power transformers, underground cables, different types of the circuit breakers, current transformer, potential transformers, capacitive voltage transformers, grounding switches, surge arresters, overhead transmission line insulators, and isolating switches. The course contains testing of the H.V. equipment, routine tests, type tests, special tests, installation and installation tests and maintenance tests. Also the course contains the maintenance regulations of H.V. components.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Apply an extensive knowledge on industrial HVAC preventive maintenance, repair and operations
  • Understand the causes of H.V. equipment failures
  • Recognize the maintenance regulations of electrical H.V. outdoor equipment and their function of operation and installation
  • Test and apply maintenance of power transformers, the current transformers, potential transformers, capacitive voltage transformers and switchgear
