The line is delivering 72 MW at 0·8 p.f. lagging.
A (medium) single phase transmission line 100 km long has the following constants :
Resistance/km/phase = 0·15 Ω
Inductive reactance/km/phase = 0·377 Ω
Capacitive reactance/km/phase = 31·87
Receiving end line voltage = 132 kV
Assuming that the total capacitance of the line is localised at the receiving end alone, determine :
(i) sending end current (ii) line value of sending end voltage
(iii) regulation (iv) sending end power factor
