Understanding Transformer Vector Groups by muaz_aminu1422 is a document available to read on EtoBox.

The vector group is a method used by the IEC to categorize the winding configurations and phase angle relationships in three-phase transformers. It uses a code with letters indicating the winding type (delta, wye, zigzag, or independent) and numbers indicating the phase angle difference between windings. For example, a Dy1 transformer has a delta-connected primary and wye-connected secondary with the secondary lagging the primary by 30 degrees. The vector group provides a simple way to understand the intern
