Question

I don't need the answer to the uploaded problem 2.44.  I know how to solve all the parts of that question.  However, my professor said to do "Prob. 2.44. Use as the reference phasor phase a to neutral voltage at the load."  What does he mean by the second part of the problem?  Do I do additional work after solving 2.44?

Two balanced three-plia.se loads that are connected in parallel are fed by a three-phase line having a series impedance of (0.4 + j2.7) ohm 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 3 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.

Explanation / Answer

It means that since load is balanced, we can solve by using per phase calculations. After that we can solve for 3 Phase by multiplying the valude obtained for single phase with 3.
