Vector groups are used to indicate the phase difference
between primary and secondary quanrtity in case of 3 phase
transformers.
Application:
On the basis of vector group, we choose the transformers
which could be operated in parallel.
Two transformer belonging to same parallel group can be
paralled only.
phase difference for various group
Group 1= 0 degree.
Group 2= 180 degree.
Group 3= -30 degree.
Group 4= +30 degree.
Depending upon the applications Star,delta or ZigZag connection
is used.Also there are many possible winding pattern even for
same connection pairs(e.g. star/delta, delta/star, delta/delta,
star/star, delta/zigzag etc).So we have inherent phase
difference with respect to each other.This difference is
technically represented by different notations.
