Question
A 3-phase, transmission line is to be built using Falcon ACSR conductor with a manugfacture data given in the
attached table. Bundeling is to be used, with three conductors per phase spaced symetrically 30cm apart and a
horizontal tower configuration is used, with a distance of 5m between adjacent phases as shown below.

5m
-5m
Assuming that the line is uniformly transposed.
(a) Determine the transmission line inductance per phase in H/km.
(b) Determine the transmission line capacitance per phase in F/km
(c) What is the thermal rating (maximum current carrying capcity) of this transmission line?
(d) What is the difference between the parametrs of overhead line and underground cables?
Given: µ0=4x10-7 H/m, 80-8.854x10-12 F/m, 1 mile=1.607km, 1 meter-3.28 feet, 1 feet-12 inches
