i need the answer quickly
Two transformers A and B, both of no-load ratio 1,000/500-V are connected
in parallel and supplied at 1,000 V. A is rated at 100 kVA, its total resistance and reactance being
1% and 5% respectively, B is rated at 250 kVA, with 2% resistance and 2% reactance. Determine
the load on each transformer and the secondary voltage when a total load of 300 kVA at 0.8 power
factor lagging is supplied.
