L-G short circuit study

(OP)
Hi, I am thinking about L-G short circuit study.But I am having some trouble with collecting those zero sequence data for the calculation.Actually, the acquisation of Zero-sequence data depends on the site instalaltion and insualtion,which make the design complicated.But sometimes, we have to run L-G s-c study in order to do some L-G fault protection relay coodinations.Who can recommend me an easier way of doing this. Thanks a lot.

It might help if we knew a little about your system topology.

SKM software (Power Tools for Windows) calculates it for you based on the type of cable, wiring method, and transformer and switchgear characteristics.
