A telephone line runs parallel to an un-transposed three-phase transmission line shown in Fig. P2.1. The power line carries balanced current of 400 A per phase. The frequency is 50 Hz. (a) (i) Determine the flux linkages of conductor "P". (ii) Determine the flux linkages of conductor "n". (iii) Determine the net flux linkages of the line. (b) Determine the total mutual inductance in mH/km. (c) Determine the voltage induced in the telephone line per km. Telephone Lines 5 m 15 m 5 m Hlm, Fig. P2.1
