What is the winding configuration of a transformer?

The combination of the connection methods for the high, medium, and low voltage windings of a transformer is referred to as the winding configuration. The winding configuration is crucial for the performance, manufacturing cost, and operational characteristics of the transformer. Common winding configurations for dual-winding three-phase transformers include Yy, Yd, and Yz; for three-winding three-phase transformers, configurations like Yyd, Yyy, Yad, and Yay are commonly used.
