Two transformers A and B of different ratings but equal voltage ratios share a load of 900 kVA at 0.8 power factor lagging at 400 V by operating in parallel. Transformer A has a rating of 600 kVA, resistive drop of 1% and reactance drop 5%. Transformer B has a rating of 300 kVA, resistive drop of 1.5% and reactance drop of 4%. Calculate the load shared by each transformer and the power factor at which it is working.
