State the difference between Three winding transformers and
Two winding transformers ? where its used?

Answer Posted / ashraf majid

Three Windings are required Where U require three levels of
voltage.These windings are
1.HV (High Voltage) Winding
2.IV (Intermediate voltage) Winding
3.LV (Low Voltage) Winding
The main task of voltage transformation is performed by HV
winding & IV winding, while as LV winding is used for minor
purposes as auxilliary winding

Two winding transformers are more common and used for
transformation of One voltage level into another.
