A three-phase transposed line is composed of one conductor per phase with flat horizontal spacing of 11 m as shown in Figure 1(a). The conductors have a diameter of 3.625 cm and a GMR of 1.439 cm. The line is to be replaced by a three-conductor bundle. The new conductors have a diameter of 2.1793 cm and GMR of 0.8839 cm. The new line will also have a flat horizontal configuration, but it is to be operated at a higher voltage and therefore the phase spacing is increased to 14 m as measured from the centre of the bundles as shown in Figure 1(b). The spacing between the conductors in the bundle is 45 cm. Determine:
(a) The percentage change in the inductance.
(b) The percentage change in the capacitance.
