Assume that a 7.2-kV, 60-Hz, single-conductor, belted cable has a
conductor diameter of 2 cm and a lead sheath with inside diameter of
4 cm. The resistivity of the insulation is 1.2 x 10^8 M-cm, and the
length of the cable is 3.5 mi. Calculate the following:
(a) Total insulation resistance in megohms
(b) Power loss due to leakage current flowing through insulation
resistance.
