Transformer is an imperative mechanism which is used in the meadow of electricity generation in all over the world and is a motionless device which transfers electrical energy from one track to another circuit without change in the frequency. The objective of this article is to present an inclusive review of a variety of aspects of transformer. This paper discusses equivalent circuit design, losses measurement, testing of device, harmonic measurement issues. The relevance of evolutionary technique and renewable energy in transformer is also presented in this paper.
