Substation grounding grids

From the grid drawing in DXF to the map of touch and step voltages, with soil stratification and fences checked section by section.

Inside the program

GridDesign screen: plan of an irregular grounding grid with the touch-voltage map, two buildings left out of the analysis and the property fence checked section by section; the three-layer soil stratification from a Wenner survey; and the touch voltage per fence section.
