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.

Frequently Asked Questions
What is CDEGS software?
CDEGS (Current Distribution, Electromagnetic Fields, Grounding, and Soil Structure Analysis) is the world's leading software suite for electrical grounding analysis, developed by SES Technologies. It is used by utilities, government agencies, and engineering firms worldwide to model complex grounding systems, calculate step and touch potentials, and ensure IEEE 80 compliance.
Why is CDEGS analysis better than manual calculations?
CDEGS models multi-layer soil structures, complex electrode geometries, and fault current distribution with a level of accuracy that manual calculations cannot achieve. For utility substations and industrial facilities, CDEGS analysis is the industry standard required by IEEE 80 and accepted by regulators worldwide.
What does a CDEGS analysis report include?
A CDEGS analysis report includes soil resistivity modeling, grounding system modeling, fault current distribution analysis, step and touch potential calculations, safety compliance verification per IEEE 80, and engineering recommendations. All reports are signed and stamped by a licensed P.E.
When is a CDEGS analysis required?
A CDEGS analysis is required for utility substations, high-voltage transmission facilities, and any site where step and touch potential safety must be formally demonstrated per IEEE 80. It is also used for telecommunications grounding, pipeline interference studies, and AC mitigation design.
