9. A 10-kVA, 2000/400-V, single-phase transformer has resistances and leakage reactances as follows:
R = 5.2 0, X, = 12.5 0, R, = 0.2 Q, X, = 0.5 0
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 phasordiagram. [376.8 V](Elect. Machines, A.M.I.E. Sec B, 1989)
