In version 35, dynamic unbalance faults are available if .seq is completed. In order to aplly a line-to-ground fault without impedance, I think that In-line fault option shoulb be chosen, and the line to ground impedance XL-G shoulb de 0. Is it correct?

On the other hand, line to groun impedance value is in Ohm? In pu? If it is in pu, the base is Zbase=U^2/Sbase? I can't find the description inthe manual.

Yes, any fault impedance is given in pu and a solid fault is entered with XL-G = 0.

The pu data system is described in manual "program Application Guide, Volume 1, Chapter 3.
