c) A three phase transmission line operated at 60HZ is arranged as shown in Figure 4. The conductors are the ASCR Pheasant. By using the conductor's characteristic in the Appendix section, determine the total inductive reactance per mile of the transmission line. Assume the length of the transmission line is in the range of 15-35 km.
