A short three-phase transmission line with the following specifications 200 kV. 100 MVA, 60 Hz. is 100 km long. The characteristic parameters of the transmission line are: resistance = 0.06 02/km, reactance = 0.9 02/km. Find the magnitude of the sending end voltage (phase value in kV) if the line supplies rated voltage and apparent power at 0.75PF leading. The voltage at the receiving end of the transmission line is 190 kV.
