Cdegs Software -

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.

It can handle any conductor arrangement, from simple rods to massive, interconnected industrial grids.

Calculates the performance of buried grounding grids under fault conditions. It computes key safety parameters such as:

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) cdegs software

Accurate modeling prevents catastrophic failures. An under-designed grid can lead to lethal step/touch potentials during a fault, while an over-designed grid can result in exorbitant construction costs. CDEGS provides the precision needed to find the balance between cost and safety.

It uses first-principle physics (Maxwell’s equations) rather than simplified empirical formulas. This makes it reliable for even the most complex geometries.

Determines the true soil structure (uniform, two-layer, or multi-layer) from field measurements. Accurate soil modeling is critical for predicting grounding system performance. CDEGS utilizes a Method of Moments (MoM) approach

(Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis) is the global industry standard for power system grounding and electromagnetic interference (EMI) analysis. Developed by Safe Engineering Services & technologies (SES), it is widely used by utility companies and consultants to ensure safety and equipment reliability. Core Capabilities

Before a grounding system can be designed, the properties of the soil must be understood.

Unlike general-purpose simulation tools, CDEGS is specifically built to solve complex problems related to the interaction between electrical networks and the physical environment (soil, air, and infrastructure). It is used extensively by utility companies, consulting engineers, and research laboratories worldwide to ensure safety and compliance with standards such as IEEE 80, IEC 62305, and EN 50522. It can handle any conductor arrangement, from simple

When high-voltage transmission lines run parallel to "victim" infrastructure—like gas pipelines, railways, or telecommunication cables—they can induce dangerous voltages. CDEGS quantifies this interference, allowing engineers to design mitigation systems to protect personnel and equipment. 3. Lightning Protection

The software is modular, meaning it can be tailored to specific engineering needs. Here are the primary ways it is used in the field: 1. Grounding (Earthing) Design
