About Course

This electrical engineering course focuses on the maintenance of power transformers used in power transmission and distribution. We begin by explaining the operating principles of a transformer before identifying the various parts of a power transformer and their function. The course explains the principles and procedures used to carry out routine and non-routine inspections on a transformer to ensure its continued operational efficiency.

We then examine common transformer faults and show you how to repair them. We identify the various types of transformers used in today’s industries, including commercial and domestic models. Above all, since transformers generate heat during operation, it is important to ensure adequate cooling. This electrical engineering course focuses on transformer cooling and discusses a range of cooling methods.

We lay out all the features of a power transformer to help you understand its full operational characteristics. This skill helps you to determine when there is a fault affecting any part of the transformer. We also outline basic maintenance techniques for a power transformer. This course suits electrical technicians, supervisors, project engineers and contractors. Sign up to acquire a valuable, practical skill.
