3 phase diode rectifier in accordance with IEC 61000-3-12


If I have a 3 phase power electronics rectifier with a 6 pulse diode bridge with a big smoothing inductor in the DC Lin, what is the minimum short circuit ratio Rsce of the grid that is needed to operate the rectifier in accordance to IEC 61000-3-12.
I already made a calculation based on the attached limits and the harmonic values of the aforementioned rectifier. Because I cannot prove the correctness because its only a calculation I would like to double-check the calculation.
