What is transformer?
A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer. Since, there is no rotating or moving part, so a transformer is a static device. Transformer operates on an ac supply. A transformer works on the principle of mutual induction.
Types of Transformer
Transformers can be categorized in different ways, depending upon their purpose, use, construction etc. The types of transformer are as follows,
- Step Up Transformer and Step Down Transformer - Generally used for stepping up and down the voltage level of power in transmission and distribution power system network.
- Three Phase Transformer and Single Phase Transformer - Former is generally used in three phase power system as it is cost effective than later. But when size matters, it is preferable to use a bank of three single phase transformer as it is easier to transport than one single three phase transformer unit.
