In Figure P16-4.9, the source and load buses are interconnected by a transmission line with wire impedance \(Z_{\mathrm{W}}\). The load at bus 2 draws an average power of \(P_{2}=600 \mathrm{~kW}\) at a lagging power factor of 0.85 and the line current is \(I_{\mathrm{L} 1}=10 \mathrm{~A}\) (rms). The source \(S_{1}\) provides \(601.8+j 387 \mathrm{kVA}\) of complex power. Find \(Z_{\mathrm{W}}\).
