4 two balanced three-phase loads that are connected in parallel are fed by a three-phase line having a series impedance of (0.4 1 j2.7) ω per phase. one of the loads absorbs 560 kva at 0.707 power factor lagging, and the other 132 kw at unity power factor. the line-to-line voltage at the load end of the line is 2200 ï3 v. compute (a) the line-to-line voltage at the source end of the line, (b) the total real and reactive power losses in the three-phase line, and (c) the total three-phase real and reactive power supplied at the sending end of the line. check that the total three-phase complex power delivered by the source equals the total three-phase complex power absorbed by the line and loads
