A factory has an electrical load of 1600 kW at a lagging power factor of 0.8 and fed from a line having an impedance of 0.05+j0.4 N. The voltage at the factory is maintained at 2150 V (rms). An additional variable power factor load is to be added to the factory. The new load will add 320 kW to the real power load of the factory. The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. Part A Find the average power loss in the line before and after the load is added. Express your answers in kilowatts to three significant figures separated by a comma. Petore, Patter= kW Part B Find the ms magnitude of the voltage at the sending end of the line before and after the load is added. Express your answers in volts to three significant figures separated by a comma. Varms beforel. Varma after= V
