Transformers play a vital link in the power delivery chain and have their own unique characteristics when compared to other distribution plant items such as switchgear which require a specific understanding and knowledge. Transformers are essentially static items with, other than tap changers, no moving parts to speak of. Appearing as very robust pieces of equipment, transformers tend to be overlooked until things go wrong.
In order to fully understand transformers, it is necessary to take a “back to basics” approach starting off with the discovery of electromagnetic interaction and early designs and history. Thus, one delves into the major components both inside and outside the main transformer tank, and an understanding of the electrical theory involved. To strengthen this aspect an actual transformer design will be conducted up to the point of active part specification (core size and windings.)
For in-service transformers aspects of the transformer oil and electrical testing (from design, construction, factory acceptance to commissioning) will be covered. Finally, an introduction to developing a maintenance strategy and implementing a comprehensive maintenance plan and the management thereof. The course also covers protection relays and mechanical devices associated with transformer protection, the understanding of the circumstances under which such protection devices operate and to be able to assess potential failures and their causes.
