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 = 0-2 Ω
Capacitive susceptance/km/phase = 0.04 x 10-4 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.
