Tom, Grounding grids, as in grounding systems for buildings, substation, and that kind of monsters. It's not a electronics specific topic, but a electrical one :) Can you help me with this? Or point me out a link or something useful? I need some models for desing or analysis (isn't the same?). Sorry for the non-specific question, I didn't figure it out it could be confused with so many topics! ThanX again!
