Nominal T method based problem - Anna university solved problem 

A 3-phase, 50-Hz overhead transmission line 100 km long has the following constants:
Resistance/km/phase
0.1 Ω
Inductive reactance/km/phase
0.20
Capacitive susceptance/km/phase 0.0410 siemen
Determine (i) the sending end current (ii) sending end voltage (iii) sending end power factor and (iv) transmission efficiency when supplying a balanced load of 10,000 kW at 66 kV, p.f. 0-8 lagging. Use nominal T method.
