Problem #4: A single phase transformer has primary and secondary impedances of (1.4 + j5.2) and (0.0117 + j0.0465) ohms, respectively. The supply voltage is 6600 V and the turns ratio is 10.6. The secondary feeds a load which draws 300 A at a power factor of 0.80 lagging. Determine (a) equivalent impedance referred to the secondary (b) secondary terminal voltage
