Don't copy from Chegg. Solve all subparts correctly else I'll downvote.

QUESTION 2
A three phase, 50Hz, 66kV overhead line conductors are arranged at the corners of a
triangle of sides 2m, 2.5m and 4.5m. The length of the line is 100km and the diameter
of each conductor is 1.24cm. Assume complete transposition of the line.
Determine:
2.1 The inductance of the line per phase.
2.2 The capacitance per phase. Given E. = 8.854 x 10-12F/m.
2.3 The charging current per phase.
2.4
Is the choice of the transmission voltage the most economical one if the
line supplies a maximum load of 9MW? Show your workings.
