A delta-wye connected three-phase transformer is rated at 38 MVA with primary and secondary line voltage ratings of 345 and 125 kV, respectively. The transformer p.u. reactance is 10%, the p.u. no-load current is 0.1, and the iron p.u. power loss is 0.06 per transfomer rating. The transformer carries a load of 21 MW at a power factor of 0.8 lagging.

(a) Draw the equivalent circuit.

(b) Determine the transformer equivalent circuit parameters at the secondary side.

(d) If the transformer is supplied by the rated voltage, compute the load current and voltage
