I will indicate the easiest approach to solve this problem, and then will demonstrate that all the "extra" data given are, indeed, consistent.
We will apply Thevenin equivalent approach to find the real (actual) fault current at the motor terminal.
The Thevenin Voltage Vth is the voltage at the fault location, that is, Vt,m = 0.9@-14 deg.
The Thevenin impedance Zth is the impedance is that measured at ...
