What Is CDEGS Software?
CDEGS is an integrated suite of engineering software tools developed for analysing electrical networks and electromagnetic phenomena involving aboveground and buried conductors.
It allows engineers to model complex grounding systems, investigate current distribution under normal and fault conditions, calculate electromagnetic fields, and evaluate electrical safety parameters.
Some of its major applications include:
- Electrical substation grounding grid design
- Soil resistivity measurement interpretation
- Ground potential rise (GPR) calculations
- Touch and step voltage assessment
- Grounding system impedance calculations
- Fault current distribution analysis
- Electromagnetic interference (EMI) studies
- Inductive coupling between power lines and pipelines
- Lightning and transient analysis
- Cathodic protection studies
CDEGS supports the modelling of complex conductor networks and soil structures, making it useful for both conventional grounding projects and advanced electromagnetic engineering studies.
Main Applications and Features of CDEGS
1. Grounding and Earthing System Design
One of the most important applications of CDEGS is the design and analysis of electrical grounding systems.
Grounding systems are essential for protecting personnel, electrical equipment, and installations against dangerous electrical potentials during power system faults and lightning events.
CDEGS helps engineers investigate:
- Substation grounding grid design
- Grounding conductor sizing and arrangement
- Grounding system resistance and impedance
- Ground Potential Rise (GPR)
- Touch voltage calculations
- Step voltage calculations
- Surface potential distribution
- Grounding system performance assessment
- Safety assessment under fault conditions
These calculations are particularly important for high-voltage substations, power plants, and industrial electrical installations.
2. Soil Resistivity Analysis
Soil resistivity is one of the most important parameters in grounding system design.
CDEGS includes specialized tools for interpreting field measurement data and developing suitable soil models.
Applications include:
- Soil resistivity measurements
- Wenner four-point method interpretation
- Soil structure modelling
- Single-layer soil modelling
- Two-layer soil modelling
- Multi-layer soil modelling
- Soil resistivity analysis for grounding grid design
Accurate soil modelling helps engineers obtain more realistic grounding system calculations.
3. Ground Potential Rise (GPR) Analysis
During an electrical fault, current flows through the grounding system and surrounding soil. This can produce dangerous voltage differences between grounded equipment and nearby locations.
CDEGS helps engineers calculate and evaluate:
- Ground Potential Rise
- Grounding grid potential distribution
- Transferred potentials
- Touch voltage
- Step voltage
- Current distribution within grounding conductors
These studies are important for evaluating electrical safety in substations and other high-voltage installations.
4. Fault Current Distribution Analysis
Not all fault current necessarily flows through the local grounding grid.
Depending on the electrical network configuration, fault current may be distributed through:
- Grounding grids
- Overhead ground wires
- Cable sheaths and metallic screens
- Transformer neutrals
- Grounding conductors
- Connected metallic structures
CDEGS provides specialized computational modules to investigate fault current distribution and determine the current flowing through different metallic paths.
This information is essential for accurate grounding design and safety assessments.
5. Electromagnetic Interference (EMI) Analysis
Electromagnetic interference can occur when electrical power systems interact with nearby metallic structures, communication cables, pipelines, and other installations.
CDEGS can be used to investigate:
- Inductive interference
- Conductive coupling
- Capacitive coupling
- Power line interference with pipelines
- Interference with communication cables
- AC interference mitigation
- DC interference investigations
- Induced voltage calculations
These studies are especially important for installations where high-voltage transmission lines and buried metallic infrastructure share the same corridor.
6. Electromagnetic Fields Analysis
CDEGS includes computational capabilities for calculating electromagnetic fields generated by energized conductor networks.
Applications include:
- Electric field calculations
- Magnetic field calculations
- Electromagnetic field distribution
- Frequency-domain analysis
- Transient electromagnetic analysis
- Underground and overhead conductor modelling
These studies can support the assessment of electromagnetic exposure and interference around electrical installations.
7. Lightning and Transient Analysis
CDEGS can also be applied to investigations involving transient electromagnetic phenomena.
Typical applications include:
- Lightning current distribution
- Transient grounding analysis
- Frequency-dependent grounding behaviour
- Electromagnetic transient studies
- Surge-related grounding investigations
These capabilities help engineers evaluate grounding system performance under conditions beyond normal power-frequency operation.
