Question

2. Two balanced three-phase loads that are connected in parallel are fed by a three-phase line
having a series impedance of (0.1+j1.4) per phase. One of the loads absorbs 500 kVA at 0.85
power factor lagging, and the other absorbs 325 kW at unity power factor. The line-to-line
voltage at the load end of the line is 3850 V. Compute the following:
(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.
