Answer to Question #322458 in Electrical Engineering for Kami Sultan

Question

A single-phase two-wire feeder 1 kilometre long supplies a load of

50 A at 0.707 p.f. lagging, 35 A at 0.8 p.f. lagging and 60 A at 0.9

p.f. lagging at distance of 250 m, 500 m and 1000 m, respectively

from the feeding end. The resistance and reactance of the feeder

per kilometre length are 0.05 and 0.2, respectively. If the voltage

at the far end is to be maintained at 230 V, determine the voltage

at the receiving end?
