CYMGRD v6.3 R3.5 is a specialized module within the CYME software suite, developed by Eaton, designed for the design and analysis of substation grounding grids. It provides engineers with tools to optimize grounding facilities while ensuring compliance with safety standards such as IEEE 80 2000, IEEE 81 1983, and IEEE 837 2002. Core Functionalities and Modules
The software is structured into distinct modules that handle different stages of grounding design:
Soil Analysis Module: Interprets field measurements to create single or two-layer soil models. It also calculates maximum permissible touch and step voltages based on user-defined parameters like fault current and surface material.
Electrode Sizing Module: Determines the minimum required size for ground conductors and rods using material libraries and ambient temperature settings.
Grid Analysis Module: Utilizes finite element analysis to calculate current diffusion for every element of the grounding grid, determining the potential rise at the soil surface.
Plotting Module: Generates 2D and 3D visual representations, including: Eaton no longer provides trials for v6
Potential Contour Plots: Color-coded displays for touch and surface voltages.
Potential Profile Plots: Graphs showing voltage variations along a straight line compared to safety thresholds. Installation and Work Environment
The v6.3 R3.x series is a Windows-based application that requires a specific license to operate, typically granted via a physical hardware key (USB) or a license string.
Hardware Requirements: Compatible with standard Windows environments, often requiring a CD-ROM for initial installation or a web-based executable.
AutoCAD Integration: CYMGRD features an interface module that allows users to alternate between the software and AutoCAD. This is essential for importing detailed substation grid layouts from *.DXF or *.DWG files.
Data Management: Users can manage multiple "Studies" within a single "Project," allowing for the comparison of different design variations to find the most economical and safe solution. Official Access and Resources
