Question

A single phase distributor 3 km long supplies a load of 160 A at 0.7 power factor lagging at its far end and a load of 100 A at 0.85 power factor lagging at its mid point. Both power factors are referred to the voltage at the far end. The overall resistance and reactance are 0.05 km and 0.2 2 km respectively. If the voltage at the far end is maintained at 230 V. calculate the sending end voltage and phase angle between the voltages at the two ends.​

Answer 1

Answer:

6.1 An 18-km 60-Hz single circuit three-phase line is composed of Partridge ... (6) What must be the sending- end voltage when the power factor is ... The line delivers a load of 60 MW at 230 kV with 0.8 power factor lagging.
