Power transformer / two-winding - 20 - 300 MVA, 33 - 275 kV
CG Two winding transformers are usually made with load tap changer that is used to keep the voltage level of the secondary side to a set level. These transformers are utilized to lower the voltage from transmission grid to distribution grid. The System / Two winding transformers have Delta stabilizing winding that is offered to some transformers for the harmonic suppression.
