Auto Transformers
An autotransformer has its primary and secondary connected each other electrically. A portion of the energy in an autotransformer comes from this connection while the balance comes directly from the supply an autotransformer is a tapped winding transformer that changes the voltage available locally to the voltage required by a particular load. Indcoil auto Transformers are also used for starting of large indication motors.
Features and Advantages:
- Its efficiency is more when compared with the conventional one.
- Its size is relatively very smaller.
- Voltage regulation of auto transformer is much better.
- Lower cost.
- Low requirements of excitation current.
Segments Supply:
- Power Stations
- Industries
- Railways
