Question:
A three-phase \(60-\mathrm{Hz}, 125-\mathrm{km}\) overhead transmission line has flat horizontal spacing with three identical conductors. The conductors have an outside diameter of \(3.28 \mathrm{~cm}\) with \(12 \mathrm{~m}\) between adjacent conductors.
(a) Determine the capacitive reactance-to-neutral in \(\Omega\)-m per phase and the capacitive reactance of the line in \(\Omega\) per phase. Neglect the effect of the earth plane.
(b) Assuming that the conductors are horizontally placed \(20 \mathrm{~m}\) above ground, repeat part
(a) while taking into account the effect of ground. Consider the earth plane to be a perfect conductor.
