Q4. A 3-phase, 60 Hz, 500-kV transmission line is 300 km long. The line inductance is 0.97 mH/km per phase and its capacitance is 0.0115µF/km per phase. Assume a lossless line. (i) Determine the line phase constant ß, the surge impedance Ze, velocity of propagation v and the line wavelength 2. (ii) The receiving end rated load is 800 MW, 0.8 power factor lagging at 500 kV. Determine the sending end quantities and the voltage regulation. (iii) Calculate the receiving end voltage when line is terminated in an open circuit and is energized
