Rework Problem 4.39 if the phase spacing between adjacent conductors is

(a) increased by \(10 \%\) to \(7.7 \mathrm{~m}\) or

(b) decreased by \(10 \%\) to \(6.3 \mathrm{~m}\). Compare the results with those of Problem 4.39.

Problem 4.39

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.
