A- A 3-ph, double circuit O.H.T.L, 320 kV, 340 km, 50 Hz has a configuration as shown in the figure below where each phase in the double circuit has a double bundle with a spacing of d cm between the two conductors in the bundle where d=44cm Each conductor in the bundle has a diameter of 0.135 ft and a geometric mean radius (Ds = 1.6 cm). Calculate: 1- Inductance per phase per km. 2- Total inductive reactance. 3- This T.L. is required to supply 240 MVA at 0.86 lag P.f. at 320 kV, assuming that this load is divided equally between these two circuits, find the voltage drop across this T.L (ignore capacitive effect in the calculation). 4- What may happen if we replace the location of a' and c' bundles. Discuss your answer. 5- Suggest a way to reduce the value of the inductance. Verify your suggestion.
