Answer Posted / gunasekaran
I1N1=N2(I2+Ie)
primary ampere turn=secondary ampere turns
when secondary is open I2 is zero so primary ampere turn is
fully used for magnetizing the core so high voltage will be
induced in the secondary then core will be saturate.then
finally it will be blast. (Ie magnetizing current)
