I. A twin-conductor circuit of three-phase 50 Hz line with horizontal spacing of 6 m. Each
sub-conductor of the bundle has a diameter of 25 mm and spacing between the sub-
conductors is 0.3 m. Each phase group shares the total current and charge equally and the
line is completely transposed. Determine the inductance per km and the line inductive
reactance per phase per km.
II. If the sub-conductors of each phase are replaced by single conductors. Calculate the
percentage decrease in inductive reactance due to bundling. Assume that the area of cross-
