1. A balanced 3-phase, Y-connected, 540 kW load at 0.8 lagging power factor is supplied through a 3-phase, Y-Y connected transformer rated at 33000/2400 V with equivalent leakage impedance of (0.26 j1.08) ohms referred to its low-voltage. The line-line voltage at the load terminals is 2200 V. The high voltage terminals of the transformer is connected to a feeder whose impedance is (105 j360) ohms as shown in Fig. 1.Calculate the transmission losses (i.e. active power consumed by the feeders)
