Transformer is one of the most vital and important electrical machinery. The development of the present day power system is very much attributable to the large number and types of transformer that are in operation in the system, such as, generator transformers, step-up transformers, step-down transformers, interlinking transformers, power transformers & distribution transformers etc. Being a static machine, it is inherently reliable compared to other machines.
