Question: Rework Problem 4.18 if the phase spacing between adjacent conductors is (a) increased by (10 %) to (7.7 mathrm{~m}) or (b) decreased by (10 %)

Rework Problem 4.18 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 4.18.

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 $\Omega / \mathrm{km}$.
