A three-phase wye-delta transformer is rated 225-kV:24-kV, 400 MVA and has a single-phase equivalent series reactance of 6.08 ohms as referred to its high-voltage terminals. The transformer is supplying a load of 375 MVA at 0.89 power factor leading at a voltage of 24 kV (line to line) on its low-voltage side. it is supplied from a feeder whose impedance is 0.17+j2.2 ohm 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 send end of the feeder.
