Answer / t. eswara rao

If the primary is DELTA connected, there is no voltage in
the secondary for this case. if primary is star connected
and star point is earthed then it depends upon the
configuration of the transformer, whether it is star-delta
or star-star.It also depends upon the star point earthing
whether it is solidly earthed or through NGR.
