A single-phase load is supplied through a feeder whose impedance is 95 + j360 N and a 35- kV/2400-V transformer whose equivalent impedance Zeg is 0.23 + j 1.27 Q referred to its low-voltage side. Use the approximate equivalent circuit of the practical transformer. The load is 160 kW at 0.89 leading power factor and 2340 V. Compute the phasor voltage Vs (expressed in polar form, in volts) at the sending end of the feeder. Refer all quantities to the high voltage side. Feoder Transformer Load 95 +j 360 0 160 kW Vs E1 E2 0.89 pf leading V = 2340 + jo v
