(b) A 3-phase, 50 Hz, 132 kV overhead line of length 150 km has conductors placed in a horizontal plane. The diameter of the conductors is 20 mm and assume complete transposition arrangement is applied. (i) Analyse the charging current per phase when the conductors spacing are set at 4 m. (ii) Investigate the range of conductor spacing that should be chosen in order to reduce the magnitude of the charging current per phase in Q2 (b)(i) by 5% or more.
