Course will introduce a full understanding to the technology of the electrical equipment to electrical personnel. It will explain the successful start-up and subsequent continued operation followed by the electrical equipment periodic inspection and testing. To successfully aware and understand the electrical maintenance principles and basics. They could successfully not only inspect and test electrical equipment but also perform diagnostics and find out the faults to fix it shortly and safely.

This will ensure the electrical equipment operates correctly so that production is maximized in a safe, cost effective and efficient manner.

Delegates are encouraged to raise queries both during and at any time after attending the course and are also asked to bring with them any technical issues that they may have.

Objective

Participants attending this program will return to their respective organizations equipped with new or refreshed skills to ensure that electrical equipment is inspected, tested and operated in safe and a fashion that ensures reduced costs.
On successful completion of this course, participants will have:

  • A better understanding of distribution system basics and operation to realize the effect of equipment faults on electric network.
  • A better understanding of maintenance purposes and types.
  • A better understanding of inspection and testing methods
  • A better understanding of the updated electrical condition monitoring.
  • A better understanding of troubleshooting procedures
  • A better understanding for the major equipment operations.
  • An improved capability in testing electric equipment.
