CDEGS Analysis
Advanced computer modeling using CDEGS software for complex grounding system analysis and design.
Service Overview
E&S Grounding Solutions employs CDEGS (Current Distribution, Electromagnetic Fields, Grounding, and Soil Structure Analysis), the leading-edge computer modeling software from Safe Engineering Services & Technologies (SES TECH). This is the same world-class software used by electric utility companies around the world for designing their substations and transmission lines.
By partnering with SES, E&S Grounding Solutions offers this same advanced analytical capability for use on your project site. CDEGS enables our engineers to perform highly accurate analysis of grounding systems under both normal operating and fault conditions — including step and touch potential analysis, ground potential rise calculations, electromagnetic interference analysis, and multi-layer soil modeling.
