Question 3) A 200 km Three-Phase 50 Hz transposed transmission line is composed of one ACSR, 1,431,000 cmil, 47/7 Bobolink conductors as shown in Figure 3 (a).The Three-Phases have flat horizontal spacing of 11 meters as shown in the Figure. The conductors have a diameter of 3.625 cm and a GMR of 1.439 cm. The Line is going to be replaced with a three conductor bundle of ACSR, 477,000 cmil, 26/7 Hawk conductors. The conductors have a diameter of 2.1793 cm and a GMR of 0.8839 cm. The new line will have an increased horisontal phese spacing of 14 meters as it is going to be operated at higher Voltage rating. The new line is shown in Figure 3 (b). The spacing between the bundles in Figure 3 (b) is 45 cm. Determine, a) The inductance for each case and the percentage change in inductance b) The inductive reactance for each line and the percentage change. c) *Comment on your results. b 11 m 11 m Figure 3 (a) a b 14 m 14 m
