How to make vector group test of transformer?
Answers were Sorted based on User's Feedback
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.

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
