hi,
iam wondering about the unity power factor ..
for example if we have a motor that will cause the power factor to be lagging by 0.3
what will happen if we add capacitor to make the power factor 1 (unity)
now we will not have any reactive power and we reduced the current to the minimum...
hi,
if we are talking about 3-phase transformer
unbalanced system or load means that the amount of the load you connect for each phase is not equal and that will cause the nutral to be not zero.
it also happens in the distribution transformer.
