As shown, the HV winding is connected in delta while the LV winding is connected in wye. Notice how the HV winding is connected in figure 4. The delta connection shown is that of a DAB where the polarity of phase winding A is connected to the non-polarity of phase winding B.
The other delta connection is the DAC where the polarity of phase winding A is connected to the non-polarity of phase winding C. Can you determine the vector group of the configuration shown in figure 1? Share your answer in the comments section below.

It also determines the high voltage and low voltage windings arrangement of three phase transformers. The three phase transformer is connected in various ways. On the basis of connection, the vector group of the transformer is determined. Three phase transformer is divided into four main groups according to the phase difference between the corresponding line voltage on the high voltage side and the low voltage sides.
Three Phase Transformer vector group explanation: Basic Idea about transformer vector group In theory of a three-phase transformer works like three equal and separated single-phase transformers working separately with three phase system with shared limbs. What is Short Circuit Test in Transformer?
