Question:

A single-phase overhead transmission line consists of two solid aluminum conductors having a radius of \(3 \mathrm{~cm}\) with a spacing \(3.5 \mathrm{~m}\) between centers.

(a) Determine the total line inductance in \(\mathrm{mH} / \mathrm{m}\).

(b) Given the operating frequency to be \(60 \mathrm{~Hz}\), find the total inductive reactance of the line in \(\Omega / \mathrm{km}\) and in \(\Omega / \mathrm{mi}\).

(c) If the spacing is doubled to \(7 \mathrm{~m}\), how does the reactance change?
