7. Three parallel three phase loads, wye connected are supplied from 208 Vrms, 60 Hz three phase supply. The loads are as follows: LOAD A: 25 kW at 0.82 pf lagging; LOAD B: 15 KVAr at 0.84 pf lag: LOAD C: 30 kVA at 0.79 pf lagging. Calculate the total phase current drawn from the supply and the capacitor needed to improve the overall power factor to 0.92 lagging if connected wye?
