The CDEGS software offers a comprehensive range of features for earthing system design and analysis, including:
The engine processes the defined geometry against the soil model. It generates the "Coefficient of Potential" matrix, solving for the current flowing in every segment of the conductor network. cdegs earthing software
✅ – Use a 2-layer soil model unless 3-layer clearly improves fit. ✅ Validate soil model – Run RESIS with multiple measurement traverses (different a-spacings). ✅ Use symmetry – Model quarter of the grid with symmetry boundaries to reduce solve time. ✅ Check GPR – If GPR exceeds 5 kV, consider soil enhancement or deep rods. ✅ Include surface layer – Add crushed rock (3 kV/m) to increase allowable touch voltage. ✅ TRALIN for current split – Don’t assume all fault current goes into your grid; overhead ground wires and cable sheaths carry significant current away. ✅ Iterate with IEEE Std 80 – CDEGS uses the same equations, but manual cross-check is wise for critical projects. The CDEGS software offers a comprehensive range of
ETAP and SKM are excellent for power flow, arc flash, and short circuit studies, but their grounding modules often rely on simplified equations. CDEGS computes the actual electromagnetic interaction between every conductor segment, making it the only choice for complex geometries, large grids, or EMI disputes. ✅ Validate soil model – Run RESIS with
