Question 1. (i) State briefly how the equivalent circuit of a generator is similar to that of a short transmission line.

(ii) On what assumptions is the representation of the following simple load supply system (FIGURE 1) based?

Fig 1

(iii) In what way does it differ from the radial supply system shown in FIGURE 2?

Fig 2

(iv) In FIGURE 1, the first transformer steps up the voltage and the second steps down the voltage. State the reason or reasons why you think this is done.

Question 2. For the following distribution feeder systems shown in FIGURES 3(i), (ii) and (iii) determine the load voltage levels.
