A 10 kVA, 2000/400 V, single-phase transformer has resistances and leakage reactance as; R1 = 5.2 Ω, X1 = 12.5 Ω, R2 = 0.2 Ω, X2 = 0.5 Ω. Determine the value of secondary terminal voltage when the transformer is operating with rated primary voltage with the secondary current at its rated value with power factor 0.8 lag. The no-load current can be neglected. Draw the phasor diagram.
