A three phase 50 Hz transmission line has impedance of (25.3+ j66.5) ohms and a shunt admittance of 4.42 x 104 mho per phase. If it delivers a load of 50 MW at 220 kV at 0.8 power factor lagging, determine the sending end voltage (a) by short line approximation (b) nominal II method (c) exact transmission line equations.
