E&S Grounding Solutions utilizes CDEGS — the Current Distribution, Electromagnetic Fields, Grounding, and Soil Structure Analysis software suite from SES Technologies — as the primary analytical tool for all grounding system evaluations. CDEGS is the industry's most rigorous true 3D electromagnetic solver, capable of modeling both above- and below-grade metallic structures with full frequency-domain and time-domain analysis.

This document provides an overview of the CDEGS software capabilities as applied by E&S engineers, including resistance-to-ground calculations, step-and-touch voltage analysis, electromagnetic interference (EMI) studies, soil structure analysis from Wenner 4-point field measurements, and corrosion analysis. It also explains how CDEGS results are used to generate IEEE Std 80-compliant grounding system designs and safety evaluations.

Understanding the analytical tools behind your grounding system evaluation is essential for interpreting results, responding to regulatory inquiries, and making informed engineering decisions. This document is intended for project engineers, facility managers, and procurement professionals evaluating grounding engineering services.
