Question
A load of 200 kW at 0.85 power factor is to be shared by two
transformers 1 and 2 having the same ratings and the same
transformation ratio. For transformer 1, the full-load resistive
drop is 1% and reactance drop 5% of the normal voltage. For
transformer 2 the corresponding values are: 2% and 6%.
Calculate the load kVA supplied by each transformer. Express
answers in polar form.
