Substation Grounding software has following capabilities:
Substation Grounding
Substation Grounding softwareis the substation grounding grid design and analysis module specially designed to help engineers optimize the design of new grids and reinforce existing grids, of any shape, by virtue of easy to use, built-in danger point evaluation facilities .
The program conforms to IEEE Std. 80-2000, Std. 81-1983 and Std. 837-2002.
Substation Grounding software can be used with:
Industrial & Transmission Analysis Software
Distribution System Analysis
Program Features
The use of Substation Grounding software allows for the rapid analysis of various design alternatives to choose an economical solution for any particular installation.
User-friendly data entry, efficient analysis algorithms and powerful graphical facilities render Substation Grounding software an efficient tool that helps the engineer arrive at technically sound and economical designs.

CADGRD, The Substation Grounding software / AutoCAD Interface module
- Substation Grounding software is a utility program accessible through the software menu structure, that allows the user to alternate between the AutoCAD and Substation Grounding software environments.
- Substation Grounding software is not a substitute for AutoCAD. In fact, AutoCAD remains a firm software requirement for Substation Grounding software, because it is AutoCAD that will produce the necessary *.DXF and / or *.DWG file that contain the pictorial description of the substation grid layout.
Simulation Results Management
-
Simulation Results Management is common to all simulation modules that generate any kind of charts. Simulation Results Management is capable of managing the outputs of different modules including Substation Grounding software.
-
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 of 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.
