How to make vector group test of transformer?

Answer Posted / mprajaneb

vector group testing: Assume that the terminals of the
primary windings are denoted as A, B, C in counter clock
wise direction and for secondary winding as a, b, c also in
counter clockwise direction. short circuit the terminals A
and a, and apply LT supply to the three terminals of HV
(Aa, B, C)
For Dy1 transformer: VbB = VcB and VbC grater than VcC.
For Dy11 transformer: VbC = VCc and VBb less than VcB.
For Yy0 transformer: VBb = VCc and VbC = VBc.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
