Answer / rasool

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.

Answer / nallakumar

It is done basically for to check the magnetically balanced
condition for the two windings as well as for phase angle
displacements for to under go in the parallal operation mode
for a transformer.
it also tells the good comparision between
Delta-star,Star-delta and Star-Star or Delta-Delta.

Answer / susant kumar acharjya

vector group analysis is to determine the plarity strength between hv side and lv side

Answer / nissi engg solution krishna

to determine the phase displacement between primary and
sencondary sides

Answer / pratik patel

For parallel operation of transformer

Answer / jigar1334

because when we connect transfomer with grid at that time phase angle should be same as grid phase angle if phase angle will different than circulating current will flow
