What is an autotransformer?


The autotransformer has only one group of coils, and the secondary coil comes out from the tap of the primary coil. Its power transmission includes not only electromagnetic induction transmission, but also electricity transmission. The number of silicon steel sheet and copper wire of this transformer is less than that of ordinary transformer, which is often used for voltage regulation.
