16–65 In Figure P16–64, the three buses are interconnected by transmission lines with wire impedances of ZW1 = 120 +

j800 Ω=phase and ZW2 = 200 + j1200 Ω=phase. The source at bus 2 produces an apparent power of j S2 j = 400 kVA at a leading power factor of 0:9. The load at bus 3 draws an apparent power of j S3 j = 650 kVA at a lagging power factor of 0:95. The line current in line 2 is IL2 =

3:25AðrmsÞ. Find the apparent power produced by the source at bus 1; the source power factor; and the line voltages at bus 1, bus 2, and bus 3.
