A three phase 50 Hz line consists of three conductors each of diameter 21 mm, The spacing between the conductors all follows: A – B = 3m, B – C = 5m, C – A = 3.6m If the line operates at 132 k V, the reactive voltampere generatd by the line per km is

The pu impedance of a line to 50 MVA, 132 kv base is 0.4, the pu impedance to a 100 MVA, 132 kv base will be
