Q1) A 1400 m, 2-core cable is used as a ring feeder supplied at both ends with 240 V. Loads of 100 A, 150 A, and 200 A are connected at points 400 m, 700 m, and 900 m, measured respectively from one end. The cable resistance (go+ return) is 0.2 Ω/km.

Calculate EACH of the following:

(a) sketch a labelled line diagram representing the distribution system; (2)

(b) the current in each cable section; (8)

(c) the voltage at each load point; (4)

(d) the total power delivered. (2)
