Question: ( 2 0 points ) The following loads are served by a balanced three - phase source: Load 1 : 2 0 kVA at 0

(20 points) The following loads are served by a balanced three-phase source:
Load 1: 20 kVA at 0.8 pf lagging
Load 2: 4 kVA at 0.8 pf leading
Load 3: 10 kVA at 0.75 pf lagging
The load voltage is 208 V rms at 60 Hz . If the line impedance is negligible, find the power factor at the source.
