rated at 4,000Kva to supply a 3-phase load of 5000kVA at a power factor of 0.8lagging.
Determine the kVA supplied by each transformer, assuming equal no load voltage is applied to
the two transformers. The percentage voltage drops in the windings at their rated loads are as
fellows: Transformer A resistance =2%; reactance =8%
Transformer B resistance =1.6%; reactance =3%
