The line of Problem 4.23 as shown in Figure 4.32 is operating at \(60 \mathrm{~Hz}\). Determine

(a) the line-to-neutral capacitance in \(\mathrm{nF} / \mathrm{km}\) per phase and in \(\mathrm{nF} / \mathrm{mi}\) per phase;

(b) the capacitive reactance in \(\Omega-\mathrm{km}\) per phase and in \(\Omega\)-mi per phase; and

(c) the capacitive reactance in \(\Omega\) per phase for a line length of \(100 \mathrm{mi}\).

Problem 4.23

Figure 4.32 shows the conductor configuration of a completely transposed three-phase overhead transmission line with bundled phase conductors. All conductors have a radius of \(0.74 \mathrm{~cm}\) with a \(30-\mathrm{cm}\) bundle spacing.
