3phase to 1phase transformer

This is an easy and a popular transformer that changing 3phase to 1phase. (Electric current U:V:W = 1:2:1)

Component

Scot connected transformer

Component

* Because of the 90°difference between each phase on the secondary side, it cannot be used in a series/parallel connection. (Type of left component symbol)

Combine 3phase and 1phase transformer

Component

In case it takes 1phase load from 3phase AC supply, R. S. T. have an unbalanced load like a below component symbol.
So we produce the special transformer in which combine a 3phase transformer with 1phase secondary soil for reducing unbalanced load.
