Description
Dear Hi,
A transformer is a static machine used for transforming power from one circuit to another without changing the frequency. As there is no rotating or moving parts, a transformer is classified as a static device. Transformer operates on an AC supply. Transformers operate based on the principle of mutual induction.
Power transformers are called heart of power system, they are essential part and required for transmission and distribution of power supply.
I have prepared this course considering theoretical and practical aspects, you will certainly feel the difference when experience professional is delivering the knowledge.
