0.4 m 795.000 cmil 26/2 ACSR b' 10 m- -10 m

Please solve part (b) (a) Suppose a completely transposed 60-Hz three-phase line has flat horizontal phase spacing with 10 m between adjacent conductors. The conductors are 1,590,000 cmil ACSR with 54/3 stranding. Line length is 200 km. Assume the line voltage is 345 kV, at 60 Hz. i) Calculate the inductance in H/m. ii) The inductive reactance in ohm/m. b) Now let’s replace the conductors of the 1,590,000 cmil conductors with two 795,000 cmil ACSR 26/2 conductors, as shown in Figure below. Bundle spacing is 0.40 m. Flat horizontal spacing is retained, with 10 m between adjacent bundle centers. Investigate that what will be the impact on transmission line parameter by changing the radius of conductor. And by applying the bundle conductors concept calculate the following; i) The inductive reactance of the line and compare it with part (a). iii) Also calculate the capacitive reactance line -to-neutral in ohm/m/phase. iv) The capacitive reactance line to neutral in ohm/phase (Throughout the Line).
