A 100 km Three-Phase 50 Hz transposed transmission line is çomposed of bundle of three ACSR, 1,431,000 çmil, 47/7 Bobolink conductors as shown in Figure 2 (a). The Three- Phases (bundled Conductors) have flat horizontal spacing of 11 meters as shown in the Eigure 2(a). The conductors have a diameter of 3.8 cm and a GMR of 1.5 cm. The Line is going to be replaced with a six conductor bundle of ACSR, 477,000 çmil, 26/7 Hawk conductors. The conductors have a diameter of 2.5 cm and a GMR of 0.9 cm. The new Jine will have a horisontal phase spacing of 14 meters as it is going to be operated at higher Veltage rating, The new line is shown in Figure 2 (b). The spacing between the bundles in Figure 2 (a) and (b) is 45 cm.

please help me step by step solve thank you

A 100 km Three-Phase 50 Hz transposed transmissioa line is composed of bundle of three ACSR, 1,431,000 çmil, 47/7 Bobolink conductors as shown in Eigure 2 (a). The Three- Rhases (bundled Conductors) have flat horizontal spacing of 11 meters as shown in the Eigure 2(a). The conductors have a diameter of 3.8 cm and a GMR of 1.5 cm. The Line is going to be replaced with a six conductor bundle of ACSR, 477,000 çmil, 26/7 Hawk conductors. The conductors have a diameter of 2.5 cm and a GMR of 0.9 cm. The new line will have a horisontal phase spacing of 14 meters as it is going to be operated at higher Voltage rating, The new line is shown in Figure 2 (b). The spacing between the bundles in Eigure 2 (a) and (b) is 45 cm. Determine. a) The capacitance for each case and the percentage change in çapacitance b) The inductive reactance for each line and the percentage change. c) Jhe inductance for each case and the percentage change in inductance 11 m (a) 11 m OLD TRANSMISSION LİNE 0.45 m 0.45 m 0.45 m 0.45 m 0.45 m 0.45 m 14 m 14 m (b) NEW TRANSMISSION LINE
