Unformatted text preview: source (60 Hz and 480 V line to line). The nature of the three loads are described below: Load #1: Wye-connected load with 100 kVA (3-phase) at 0.9 PF lag; Load #2: Wye-connected load with 60 kW (3-phase) at 0.7 PF lead; Load #3: Delta-connected load, with 75 A phase current and 0.9 PF lag. Calculate the following: a) The total complex power (3-phase) consumed by the three loads b) The magnitude of the total source line current (answer: 300 Amps) c) The capacitive reactive power per phase needed to be added to the delta connected load to make the overall PF equal to 1.0 (total for all loads). d) The magnitude of the total source line current after the power factor correction of part c)...
