Two 6600/250-V transformers have the following short-circuit characteristics: Applied voltage 200 V, current 30 A, power input 1,200 W for one of the transformers; the corresponding data for the other transformer being 120 V, 20 A, and 1,500 W. All value are measured on the H.V. side with the L.V. terminals short-circuited. Find the approximate current and the power factor of each transformer when working in parallel with each other on the high and low voltage sides and taking a total load of 150 kW at a p.f. of 0.8 lagging from the high voltage bus bars.
