Answer / msalam_shahin

because the flux cuts the voltage with the adjescent limbs.
say if we apply voltage in r-n leads of star connected
secondary then we can get almost 80% voltage in y-n lead
and 20% VOLTAge in b-n leads. Because the b-phase is far
away from y-phase from r-phase.... this the reason.....

The magnetic balance test is carried out on transformer for
detection of shorted turns and core problems.As the results
recorded on individual phases are compared ,test voltages
should be the same for each phase

what will happen if the input of a transformer is dc?
