transformer is located.
The actual phase shift is achieved by the interconnection of two phases of the star-connected regulating windings across one phase of the delta connected booster winding. By on-load tap changing, the magnitude and polarity of the phase shift can be modified, which in turn determines the circulating current in the system. For lower power ratings the two active parts may be placed in a single tank.
However, in higher power phase shifting transformers, the two active parts
