The source has an abc-phase sequence. At the wye-connected load, the phase-a voltage Va'n' has phase angle (theta)a'n' = 60 degrees and the phase impedance is (10 + j15) ohms. Further, the line impedance per phase is (1.1+ j1.5) ohms and the total power loss in the three lines is 480 W.

(a) Draw a well-labeled diagram to illustrate the per-phase analysis of the power transmission system.
(b) Determine the complete set of phase voltages at the wye-connected source.
