7. The balanced three-phase source in Figure 7 produces an average power of 100 (kW). The line impedance is Zw = 1+ j7 (Q/phase) and the balanced load has an impedance of Zy = 200+ j100 (22/phase). Find the line voltage at the load, and the complex power delivered to the load. IL Zw Balanced IL Three-phase Zw Source Balanced Three-phase Load L Zw Figure 7. Circuit for problem 7.
