The positive, negative and zero sequence impedances of a 125 MVA, three-phase, 15.5 kV,
star-grounded, 50 Hz generator are 𝑗0.1 pu, j0.05 pu and j0.01 pu respectively on the
machine rating base. The machine is unloaded and working at the rated terminal voltage. If
the grounding impedance of the generator is j0.01 pu, then the magnitude of fault current
for a b-phase to ground fault (in kA) is __________ (up to 2 decimal places).
