-0.33 marks
A two machine power system is shown below. Transmission line XY has positive sequence Impedance of and zero sequence impedance of .
An 'a' phase to ground fault with zero fault impedance occurs at the center of the transmission line. Bus voltage at X and line current from X to F for the phase 'a', are given by Volts and Amperes, respectively. Then, the impedance measured by the ground distance relay located at the terminal X of line XY will be given by
