Usually, between neutral and a phase is a smaller voltage, and between two different phases is a larger voltage.

In that picture, winding elements that appear parallel are wound on the same core segment, and so constitute a single phase transformer. 3-2. .

. In this type of connection, both the three phase primary and secondary windings are connected in delta as shown in the Figure 1: The voltages on primary and secondary sides can be shown on the phasor diagram ( Figure 2 ): This connection proves to be economical for large low voltage transformers as it increases number of.
