Q1. A 525 m, two core distributor cable is fed at one end with 240 V. d.c and at the other end with 250 V. d.c. The following loads are applied at distances measured from the 240 V end:

Load 1 10 A at 100 m

Load 2 100 A at 250 m

Load 3 70 A at 450 m

Load 4 75 A at 500 m

The cable resistance (go and return) is 0.16 Ω per 100 m.

Calculate EACH of the followings:

(a)The current supplied at each end of the distributor; (6)

(b)The voltage at each load point; (8)

(c)The power delivered at each end of the distributor. (2)
