Solve: A 50 Hz three-phase transmission line is 300 km long. It has a total series impedance of 23+j 750 and a shunt admittance of j500 ms. It delivers 150 MW at 220 kV with a power factor of 0.88 lagging. Find the voltage at the sending end using: (a) short line approximation, (b) medium line (nominal pi) approximation, and (c) long line model.
