The capacitance of a single-circuit, three-phase transposed line with the configuration shown in Figure 4.38, including ground effect, and with conductors not equilaterally spaced is given by

(a) Now consider Figure 4.39 in which the configuration of a three-phase, single circuit, \(345-\mathrm{kV}\) line with conductors having an outside diameter of 1.065 in. is shown. Determine the capacitance to neutral in F/m, including the ground effect.

(b) Next, neglecting the effect of ground, see how the value changes.
