Determine the magnitude of the phase voltage vab and the


For the balanced three-phase system shown below, it is determined that 120 W is lost in each wire. If the load draws a total complex power (all three ZP loads) of 25 kVA at a lagging PF of 0.80 and the magnitude of the phase current IAB = 30 A rms. determine the following;

a) The magnitude of the phase voltage VAB.

b) The value of the wire resistance Rw.

c) The total complex power delivered by the source. What is the power factor at the source an state whether is leading or lagging.
