Question

A building inventory identified the following equipment with the corresponding impedance or power consumption at 230 V rms. The building power supply is 230 V rms. (Assume that the building voltage supply is the reference phasor) What is the total complex power consumed within the building and the effective power factor? Load 1: 160 - j40  Load 2: 500 VA at 0.85 pf lag Load 3: 450 W at 0.95 pf lead Load 4: 200 + j300 VA
