CDEGS software represents the pinnacle of electrical engineering simulation for grounding and electromagnetic interference. While it requires a high degree of technical expertise to operate effectively, its ability to model complex soil structures and electromagnetic interactions makes it an indispensable tool for modern power system engineers. It ensures that the critical infrastructure powering society does so safely, reliably, and in compliance with global standards.
As power lines and pipelines often share corridors, electromagnetic interference becomes a critical safety and integrity issue.
(Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis) is a powerful, integrated engineering software package developed by SES (Safe Engineering Services & technologies ltd.) . It is widely recognized as the gold standard for the analysis and design of grounding systems, electromagnetic interference (EMI), and soil characterization. cdegs software
It uses first-principle physics (Maxwell’s equations) rather than simplified empirical formulas. This makes it reliable for even the most complex geometries.
This is the most utilized aspect of the software, focusing on the safety of substations and facilities. As power lines and pipelines often share corridors,
Whether you are designing a substation grounding grid or protecting a pipeline from a nearby power line, CDEGS provides the mathematical rigor needed to ensure the system performs safely under both normal and fault conditions. Key Applications of CDEGS
This is the most common use for CDEGS. It calculates "Ground Potential Rise" (GPR) and helps engineers determine if step and touch voltages stay within safety limits (like those defined by IEEE Std 80). It can model complex soil structures, including multilayered or finite volume soils. 2. Electromagnetic Interference (EMI) What is CDEGS?
CDEGS utilizes a Method of Moments (MoM) approach. It calculates the current distribution in the conductors and subsequently computes the resulting electromagnetic fields and scalar potentials. This allows for high-frequency analysis (up to several MHz), making it suitable for both 50/60 Hz power frequency faults and lightning surge studies.
