In Figure P16-4.9, the source and load buses are interconnected by a transmission line with \(Z_{\mathrm{W}}=40+j 280\) \(\Omega /\) phase. The load at bus 2 draws an apparent power of \(\left|S_{2}ight|=\) 3 MVA at a leading power factor of 0.8 and the line voltage at bus 2 is \(V_{\mathrm{L} 2}=230 \mathrm{kV}(\mathrm{rms})\). Find the apparent power produced by the source at bus 1 , the source power factor, and the line voltage at bus 1 .
