Power Transformer

 

What is a Power Transformer ?

The transformer which is used on transmission lines for transmission and distribution of relatively large quantities of energy are called power transformer. It is used for power generation and transmission system.The voltage rating of the power transformer is generally above 11 KV.

50 MVA 132/33 KV Power-Transformer
