| Module | Purpose | |--------|---------| | | Interpret soil resistivity measurements (Wenner/Schlumberger) → determine multilayer soil model | | MALT | Analyze low-frequency grounding systems (DC to ~1 MHz) – main earthing design tool | | TRALIN | Calculate fault current distribution among overhead lines, cables, and grounding grids | | FFTSES | High-frequency / transient analysis (lightning, switching surges) | | HIFREQ | Frequency-domain analysis from DC to GHz (EMC, interference) | | SESConverter | Import/export CAD, GIS, and other formats |
MALT is the primary module for DC and low-frequency AC grounding analysis. cdegs earthing software
HIFREQ is a full-wave electromagnetic field solver. | Module | Purpose | |--------|---------| | |
The accuracy of any earthing calculation depends entirely on the soil model. CDEGS offers sophisticated soil analysis engines: and cable sheaths .
While CDEGS is the premier tool, it comes with challenges:
Determines how fault current splits between the grounding grid and other metallic paths like shield wires, neutrals, and cable sheaths .
