Measure phase and line voltages. Measure currents in the three lines and neutral. Measure total power dissipated in the load. Calculate total apparent power absorbed by the load. Determine power factor. Draw phasor showing voltages and currents. P=P1 + P2 Q = √3(P2 - P1) |S| = √(P2+Q2) θ = tan-1(Q/P) Measurements taken VP = 150V VL = 265V IL = 2.5A IN = 0A P1 = 645W P2 = 645W So, P = 645 + 645 = 1290W Q=√3(645 - 645) = 0 VAR ???
