A three-phase Y-? transformer is rated 225-kV: 24-kV, 400 MVA and has a series reactance of 11.7 ? as referred to its high-voltage terminals. The transformer is supplying a load of 325 MVA, with 0.93 power factor lagging at a voltage of 24 kV (line-to-line) on its low-voltage side. It is supplied from a feeder whose impedance is 0.11 + j 2.2 ? connected to its high-voltage terminals. For these conditions, calculate

(a) The line-to-line voltage at the high-voltage terminals of the transformer and

(b) The line-to-line voltage at the sending end of the feeder.
