Rework Problem 4.8 if the diameter of each conductor is (a) increased by (20 %) to (1.8

Question:

Rework Problem 4.8 if the diameter of each conductor is

(a) increased by \(20 \%\) to \(1.8 \mathrm{~cm}\) or

(b) decreased by \(20 \%\) to \(1.2 \mathrm{~cm}\) without changing the phase spacing. Compare the results with those of Problem 4.8.

Problem 4.8

A 60-Hz, single-phase two-wire overhead line has solid cylindrical copper conductors with a \(1.5 \mathrm{~cm}\) diameter. The conductors are arranged in a horizontal configuration with \(0.5 \mathrm{~m}\) spacing. Calculate in \(\mathrm{mH} / \mathrm{km}\).
