Given: Two separate transmission lines, “A” and “B” are of the same material, wiresize, impedence and length. Transmission line “A” carries 69,000 volts. Transmission line “B” carries 138,000 volts. The input power to both lines is the same. Disregarding corona losses, which of the following statements concerning power loss is correct?
