A power transformer is a type of transformer that is used to transmit electrical energy between the distribution primary circuits and the generator. These transformers are used in distribution networks to connect step-down and step-up voltages.
The main function of 138kV and 132kV power transformers is to convert and transmit electrical energy. It can convert a specific value of AC voltage into another value of AC voltage, or convert AC voltage into DC voltage.

Power Transformer
Applications of Power Transformers
- The power transformer is mainly used in electric power generation and at distribution stations.
- It is also used in Isolation transformers, earthing transformers, six pulse and twelve Pulse rectifier transformers, solar PV farm transformers, wind farm transformers and in Korndörfer autotransformer starter.
- It is used for reducing power losses during electric power transmission.
- It is used for high voltage step-up and high voltage step-down.
- It is preferred during long-distance consumer cases.
- And preferred in cases where load runs at full capacity 24x7.
