Answer / nagaraju

Hi,
Three Phase star connected or delta connected windings are
divided with phase angle i.e 360/3=120. So in A.C the phase
sequence is changing alternatively. But any time if you do
the Vector sum of the three componenets Result is zero. If
not spark will occur in that situation....

Answer / kundan

at a time when all three phase are live,they have pik valyu
is +x,-x and 0. that mean if r is +50 that time b is -50
and y is 0, all calculation is =50-50+0=0. so total
voltage is 0 v.
if this is not real ans pls send me accual fact.
