Given the broad topic of grounding systems, terms like Clean Earth, Dirty Earth, Floating Earth, Single Point Ground (SPG), Multi-Point Ground (MPG), TBB, TMGB, TGB, Star Bonding (STAR), Mesh Bonding (MESH), MBN, IBN, GPR, SRG ... frequently appear in engineering documents. Various software such as ETAP, SGW, SDWorkstation, CDEGS, etc., are offered by different companies for grounding system design. Most grounding system design engineers are familiar with ETAP and CYMGRD software. Some issues with these software include:

CYMGRD is software for designing and analyzing grounding systems, created to help engineers optimize new network designs and strengthen existing networks of any shape. Advanced features in a graphical environment combined with efficient analysis algorithms make this software a powerful tool for engineers to develop technical and economical designs.

This software allows design of grounding for substations, power plants, factories, and buildings. Design can be for uniform or two-layer horizontal soils and calculates touch and step voltages based on IEEE standards.

For grounding calculations of solar power plants, considering that panel structures are part of the grounding system, calculations differ somewhat from typical substation grounding.

The software receives fault current magnitude and duration, soil resistivity, and body weight from the user and performs the following operations using soil, network, and diagram modules: 1- Soil Module Measures soil resistivity based on one or two-layer models. This module can plot measured and calculated resistivity and calculates maximum virtual touch and step voltages according to standards. 2- Network Module Calculates current injected by each conductor into the soil and determines soil surface potential using these currents. The grounding grid can be defined as a single conductor or a set of conductors connected in a square. Substation layout can be drawn in 2D or 3D. Underground pipes and adjacent grounding grids can also be considered to see their impact on fault current and surface voltage. 3- Diagram Module Summarizes soil resistivity and surface potential analysis results on the display and uses 2D and 3D color graphics for better presentation.

Key features of CYMGRD software:

• Grounding system design for low frequencies (especially substation grounding design according to IEEE 80-2000)
• Supports IEEE 80 2000, IEEE 81 1983, and IEEE 837 2002 standards
• Finite element analysis of conductors and rods in grounding grids
• Calculation of station ground resistance (Rg) and Ground Potential Rise (GPR)
• Touch and surface potential analysis inside and outside the grid with color display
• Step voltage analysis
• Supports symmetrical or asymmetrical grids of any shape
• Modeling of return and distinct electrodes
• Calculation of maximum single-phase to ground fault current for a specified grid
• And more...

The CYMGRD/AutoCAD® Interface module The CYMGRD / AutoCAD® Interface module allows the user to alternate between the AutoCAD® and the CYMGRD environments. This utility is not a substitute for AutoCAD®. In fact, AutoCAD® remains a firm software requirement for CADGRD, because it is AutoCAD® that will produce the necessary *.DXF or *.DWG file(s) that contain the pictorial description of the substation grid layout realized with the CYMGRD software.

Simulation Results Management The charts functionality allows:

• Graphical comparison of deduced soil model with field measurements, for model acceptance
• Color-coding of the surface potential gradients based on user-defined thresholds for touch or surface potentials. Any area of the grid can be selected with the mouse for detailed calculations and danger point evaluation
• Equipotential contours for surface potentials in either 2-D or 3-D plots, with facilities to examine the graphs from any desired viewing angle
• Graphics of touch and step voltage variation along any straight line, with comparison to the safe values computed by the safety assessment module
• Graphic indications on the 2-D grid layout of the area being analyzed for touch and step voltages, for easy identification of hazardous locations

CYMCAP Software: CYMCAP software is used for precise calculation of capacity and heat rating of power cables. Its accuracy increases confidence during cable installation upgrades and new cable design. It also enhances system reliability and supports proper use of installed equipment. CYMCAP performs thermal capacity and temperature rise calculations for power cable installations. Determining the maximum current cables can carry without damaging their electrical properties is crucial for electrical facility design. This software is jointly developed by Ontario Hydro (Hydro One), McMaster University, and CYME International under the Canadian Electricity Association.

Selecting the correct cable size in projects is one of the most important engineering tasks, often done without software. If the chosen size is smaller than needed, cable damage or system malfunction may occur; if oversized, despite proper operation, economic design considerations are neglected. Usually, engineers size cables based on voltage drop and short circuit criteria, neglecting thermal sizing.

For thermal sizing, especially for MV and HV cables, cable construction and layer specifications must be accurately modeled, and allowable current calculated based on installation environments like underground, air, tunnels, ducts, trenches, etc.

This course uses the professional cable sizing software CYMCAP to introduce various cable aspects, steady-state sizing, transient sizing based on current profile, estimation of temperature field around cables, calculation of magnetic flux density around cables, induced voltage on shields, optimizing cable layout in duct banks, cable impedance matrix calculation, etc., based on IEC60853, IEC 60287 standards and Neher-McGrath method.
