Accurate grounding design starts with understanding the soil. enables engineers to input soil resistivity measurements taken at different depths and automatically calculates the resistivity and thickness of a two-layer soil model. This is crucial because soil composition heavily influences ground grid performance. 2. Ground Grid Design and Editing
