Assume that a 5 mile long feeder is supplying a 2000 kVA load of increasing load density starting at a substation. If the K constant of the feeder is given as 0.00001%VD per kVA·mi, determine the following:
(a) The percent voltage drop in the main.
(b) Repeat part (a) but assume that the load is a lumped-sum load and connected at the end of the feeder
(c) Repeat part (a) but assume that the load is distributed uniformly along the main.
