PROBLEM: • A 2,000-KVA transformer (A) is connected in parallel with a 4,000-KVA transformer (B) to supply a 3-phase load of 5,000 KVA at 0.8 p.f. lagging. Determine the KVA supplied by each transformer assuming equal no-load voltages. The percentage volt drops in the windings at the rated loads are as follows: Transformer A: resistance 2%; reactance 8% Transformer B: resistance 1.6%; reactance 3%
