## Description

The design of a transformer requires not only electrical knowledge but also mechanical and heat engineering skills. For the success of a project the electromagnetic as well as the mechanical and thermal calculation are equally important and none of them can be neglected.

Furthermore, the study of any electrical construction is not a problem of pure physics, but an engineering challenge and involves economic equations which bring two contradicting criteria; the minimum cost of construction and the minimum cost of ownership into design considerations. As in many other engineering activities, designing a transformer is not a simple application of mathematical formulas. In such a case all transformers would have been identical.

This lesson gives an overview of the main issues involved in the design of power transformer in order to provide the students with the tool for understanding the power transformer build up and operation as well as main sizing considerations.
