Three loads are connected in parallel across a 1400-V rms, 60-Hz single-phase supply as shown in Figure 2.8. I 11 12 13 Load 1: Inductive load, 125 kVA at 0.28 power factor. Load 2: Capacitive load, 10 kW and 40 kvar. 1400 V 1 2 3 Load 3: Resistive load of 15 kW. (a) Find the total kW, kvar, kVA, and the supply power factor. (b) A capacitor of negligible resistance is connected in parallel with the above loads to improve the power factor to 0.8 lagging. Determine the kvar rating of this ca- pacitor and the capacitance in μF.
