Comparing Cdegs With Xgslab Jun 2026

: Case studies on Earth Potential Rise (EPR) showed a difference as low as 0.03% to 0.27% between CDEGS HIFREQ and XGSLab XGSA_FD.

XGSLab includes a robust "Scenario Manager" that allows engineers to run multiple design variations (e.g., different grid sizes, different soil resistivity assumptions) side-by-side. This is incredibly useful for optimization studies. comparing cdegs with xgslab

| Feature | CDEGS | XGSLab | |---------|-------|---------| | Soil structure modeling | Horizontal/Vertical/Anisotropic layers, finite element | Horizontal/Vertical layers, finite element, 3D | | Frequency range | DC to GHz | DC to MHz (extendable) | | Grounding analysis | Yes (RESAP, MALT, MALZ) | Yes (Grounding, HiFreq) | | Electromagnetic fields | Full (electric/magnetic, near/far field) | Yes, with focus on power frequency & harmonics | | Lightning transients | Yes (FFTSES, ROW) | Yes (Transient) | | Interference (pipelines, rails) | Yes (SESEnviro, SPLITS, CORR) | Yes (Interference, MultiLine) | | CAD/Geographic import | DXF, SHAPE, raster | DXF, DGN, SHP, KML, raster | | Scripting/automation | SESEngine (Python/C++/COM) | COM, Python API | | Licensing | Modular, hardware key | Modular, software key (also rental) | : Case studies on Earth Potential Rise (EPR)

Both tools handle complex soil structures, but their limits differ: | Feature | CDEGS | XGSLab | |---------|-------|---------|

Unlike CDEGS, which relies on distinct modules for different tasks, XGSLab integrates grounding, electromagnetic fields, and lightning/surge analysis into a single cohesive environment. You can switch between calculating touch voltages and analyzing lightning surges within the same project file seamlessly.
