Solution
A single phase transformer is excited with rated voltage and frequency.The exciting current drawn is given as 2√2 sin ωt + 0.8√2 sin 3 ωt + 0.5√2 sin 5 ωt. A bank of such three transformers is connected in star to a balanced 3 phase, 4 wire system having a line voltage same as the rated voltage of the transformer. The neutral current in ampere is ___________.
