Problem 5: Three single-phase, 50 kVA, 2400:240 V transformers each have a leakage impedance of 0.78+j0.97 on their high voltage winding and 0.0072+j0.0095 on their low voltage side. The transformers are connected in a 3-150 kVA bank to step down the voltage at the load end of a feeder whose impedance is 0.14 + j0.97 / Phase and whose line-to-line voltage is 4160 V at the sending end. The secondary sides of the transformers supply a balanced 3- load through another feeder whose impedance is 0.0006+j0.0021. The load draws rated current from the transformers with a lagging power factor of 0.6 / phase. Neglecting Re and Xmi.e.RoXo, find the line-to-line voltage at the load when.
