A 300 km, 3-phase, 50Hz transmission line has spacing as shown in Figure. Each phase of the line consists of a bundle of three conductors.
(a) Find the total per-phase inductance and the total per-phase shunt capacitance of the line if the conductors have diameter of 2.4cm and a GMR of 0.88cm. Assume bundle spacing
d = 0.4m.
(b) Find the % change of the resistance, inductance and the capacitance if the line is modified by adding one more conductor of the same size and type to the bundle.
(c) Use Matlab to check your results in (a) and( b). Comment if the results agree or not.
Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
