A balanced three-phase source serves three loads as follows: Load 1: 24 kW at 0.6 lagging power factor Load 2: 10 kW at unity power factor Load 3: 12 kVA at 0.8 leading power factor If the line voltage at the loads is 208 V rms at 60 Hz, we wish to determine the line current and the combined power factor of the loads.
