Attempt the following pop question
A 3phase transmission line 200 km long has the following constants
•Resistance / phase / km=0.16 ohms
•Reactance/phase/km= 0.25 ohms
•Shunt admittance/ phase/ km =1.5 *10-6 S.
Calculate by rigorous method the sending end voltage and current when the line is delivering a load of 20 MW at 0.8 p.f. lagging. The receiving end voltage is kept constant at 110 kV.
