Two loads are connected in parallel across a 25-kV three-phase supply. Load 1: 1050 kW at 0.78 power factor lagging Load 2: 300 kW at power factor of 0.82 leading 1) Find the total complex power of the two loads 2) Calculate the power factor of the combined load. 3) A delta-connected capacitor bank is connected in parallel with the loads to raise the power factor to 0.98 lagging. Find the capacitor total KVAR and the capacitance per phase in microF.
