Phase rotation is always anti clockwise. (international adopted convention) Use the hour indicator as the indicating phase displacement angle. Because there are 12 hours on a clock, and a circle consists out of 360°, each hour represents 30°.
Understanding Vector Group of Transformer (Part 1)
The primary windings are connected in one of several ways. The two most common configurations are the delta, in which the polarity end of one winding is connected to the non polarity end of the next, and the star, in which all three non polarities (or polarity) ends are connected together.
