Q4. A two-core feeder cable 1200 m long has a resistance (‘go and return’) of 0.005 Ω /100 m and is fed at each end with 440 V. It supplies the following loads at the distances given, all measured from the same end of the feeder.

(i) 200 A at 400 m

(ii) 150 A at 700 m

(iii) 250 A at 1000 m

Calculate EACH of the following:

(a) The current supplied at each end of the feeder cable;

(b) The p.d. across the 150A load;

(c) The power loss in the feeder cable.
