Medium transmission line based problem- Anna University solved problem

A (medium) single phase transmission line 100 km long has the following constants:
Resistance / r = 0.25Omega
Susceptance/ m = 14 * 10 ^ - 6 siemen;
Receiving end line voltage = 66,000 V
Assuming that the total capacitance of the line is localised at the receiving end alone, determine (1) the sending end current (ii) the sending end voltage (in) regulation and (iv) supply power factor. The line is delivering 15,000 kW at 0.8 power factor lagging. Draw the phasor diagram to illustrate your calculations.
