Cdegs Software ((better))
CDEGS Software: The Industry Standard for Grounding and Electromagnetic Analysis CDEGS (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. Core Capabilities CDEGS is not a single program but a suite of engineering tools that address complex low-frequency electromagnetic problems. Its main modules include:
Soil Resistivity Analysis (RESAP): Determines the true soil structure (uniform, two-layer, or multi-layer) from field measurements. Accurate soil modeling is critical for predicting grounding system performance.
Grounding Analysis (MALT/MALZ): Calculates the performance of buried grounding grids under fault conditions. It computes key safety parameters such as:
Ground potential rise (GPR) Touch and step voltages Grid resistance Conductor currents and fault current distribution cdegs software
Line/Cable Constant Calculation (HIFREQ): Computes the electrical parameters (resistance, inductance, capacitance, and conductance) of overhead lines, cables, and pipe-type cables over a wide frequency range.
Electromagnetic Interference (EMI) Analysis (HIFREQ & SPLITS): Analyzes inductive, capacitive, and conductive coupling between power lines, pipelines, railways, and communication cables. This is essential for mitigating AC interference on nearby metallic structures.
Fault Current Distribution (SPLITS): Determines how fault currents split between overhead ground wires, neutrals, earth return paths, and other parallel paths. CDEGS Software: The Industry Standard for Grounding and
Key Applications CDEGS is used extensively in the following areas:
Substation Grounding Design: Ensuring safety for personnel and equipment during fault conditions. Power Plant Earthing: Designing robust grounding systems for generation facilities. Transmission & Distribution: Optimizing tower footing resistance and mitigating step/touch voltages. Pipeline Integrity: Assessing and mitigating AC corrosion and safety hazards due to nearby power lines. Railway Systems: Analyzing stray current and inductive interference with signaling systems. Lightning Protection: Evaluating transient responses of grounding systems to lightning strikes (via its transient module).
Advantages & Limitations Advantages:
Unmatched accuracy for complex, multi-layered soil structures. Integrated environment combining DC, AC (50/60 Hz), and high-frequency (up to several MHz) analysis. Extensive output including color contour maps, 3D visualizations, and detailed reports. Validated by decades of peer-reviewed research and field testing.
Limitations:
