Question: 2 . A 2 0 0 km , 2 2 0 kV , 6 0 Hz three phase line has a per phase series impedance,

2. A 200km,220kV,60Hz three phase line has a per phase series impedance, Z =0.032+ j0.35/km and a per phase shunt admittance Y = j4.2 x 10^-6S/km. At full load, the line delivers 250MW at 0.9 power factor lagging and at 320kV. Using the nominal pi circuit, find sending end voltage and current per phase
