Calculate the capacitance-to-neutral in \(\mathrm{F} / \mathrm{m}\) and the admittance-to-neutral in \(\mathrm{S} / \mathrm{km}\) for the three-phase line in Problem 4.18. Also calculate the linecharging current in \(\mathrm{kA} /\) phase if the line is \(110 \mathrm{~km}\) in length and is operated at \(230 \mathrm{kV}\). Neglect the effect of the earth plane.

Problem 4.18

A \(230-\mathrm{kV}, 60-\mathrm{Hz}\), three-phase completely transposed overhead line has one ACSR \(954 \mathrm{kcmil}\) conductor per phase and flat horizontal phase spacing, with \(7 \mathrm{~m}\) between adjacent conductors. Determine the inductance in \(\mathrm{H} / \mathrm{m}\) and the inductive reactance in \(\Omega / \mathrm{km}\).
