(a) A 3-phase, 50 Hz, 220 kV overhead transmission line is 300 km long. Per km inductance and capacitance of the line per phase are 1 mH and 0.01 uF, respectively. Assuming the line to be lossless, find the propagation constant per km, characteristic impedance, velocity of propagation of current and voltage waves along the line, and the wavelength of those waves.
