1) the purpose of transformers based on vector group. (e-g)
for distribution purpose it is Dyn11

2)when your going to synchronise the two transformers it
must be the same vector group.

3) it is a common point that to measure the place
dispalacement between primary voltage and equlivalent
secondary voltage.
