(i) The A, B, C, D constant of a 220 kV line are:
A = D = 0.85<1°, B = 130<73°, C = 0.001<90°. If the sending end voltage of the line for a given
load delivered at nominal voltage is 240 kV, then find the percentage voltage regulation of
the line.
(ii) In a 400 kV network, 370 kV is recorded at a 400 kV bus. Find the reactive power
absorbed by a shunt reactor rated for 40 MVAR, 400 kV connected at the bus.
(e) A 3-phase double circuit line is shown in the given figure. The diameter of each conductor
is 2 cm. Determine the capacitance and charging current per km length of the line, assume
that the line is transposed and the operating voltage 220 kV.
