Types Of Transfomer

                            Power  transformers are given a variety of different names , depending on their use in power systems.

Unit Transformer

A transformer connected to the output of generator and used to step up  its voltage is to transmission levels ( 110 kV) is sometimes called a unit transformer.

Substation Transformer

The transformer at the other end of the transmission line , which steps the voltage down from transmission levels to distribution level (from 2.3 to 34.5 kV) is called a substation transformer.

Distribution Transformer

The transformer that takes the distribution voltage and steps it down to the final voltage at which the power actually is used (110,208,220 kV) is called distribution transformer.
