Introduction:

Generally a transformer is an electrical device or machine which inductively transfers the electrical power operating at a particular current and voltage of one circuit to the other circuit which is operating at different current and voltage level. Most of the transformers are manufactured such that their characteristics must match for special application requirements such as constant current, constant voltage, higher impedance, etc.

The most common types of transformers found in electrical transmission systems, industries and electronic applications include power transformers, instrument transformers, tap changing transformers, auto transformers, RF transformer, audio transformers, etc. They all are different in size, ratings and shape with one another but the basic principle of operation of all these are same. The various types of transformers are discussed in this article so let us have a look on them.
