20KVA Step Down Three Phase Auto Transformer 480V/220V/208V/120V/110V
Feature:
The autotransformer is a transformer with only one winding. When used as a step-down transformer, a part of the turns are drawn from the winding as the secondary winding. When used as a step-up transformer, the applied voltage is only applied to part of the turns of the winding. Usually the part of the winding that belongs to both the primary and the secondary is called the common winding, and the rest of the autotransformer is called the series winding. Compared with the ordinary transformer, the autotransformer of the same capacity is not only small in size, but also more efficient, and the transformer The larger the capacity and the higher the voltage, the more prominent this advantage. Therefore, with the development of power systems, the improvement of voltage levels and the increase of transmission capacity, self-coupling transformers have been widely used due to their large capacity, low loss, and low cost.
