SES regularly publishes technical papers injournals and presents papers at various internationalconferences on engineering topics related to power systemgrounding (including analysis of transients and lightning), EMFstudies and AC interference. SES also undertakes landmarkapplied R&D studies in these areas. These studies have notever been undertaken before with the accuracy and detail ofwhich our modern computer-based technology is capable. ThisR&D is now being distilled into " " engineering manualsat a level of detail designed for both novices and advancedusers who encounter similar problems and wish to model themwith SES software.

This powerful, yet easy-to-use software package provides a simple, integrated andautomated environment for carrying out grounding studies. It consists of several integratedengineering modules that are designed to study the effectiveness of grounding installationswith respect to electrical safety of both personnel and equipment, allowing you to suggestimprovements to existing installations or design new installations. Flexible data reporting andgraphing utilities allow you to collect and illustrate any aspects of the results that areimportant to your work. The program computes and reports the earth potentials, touch andstep voltages, fault current distribution in the adjoining circuits, etc…

The component-based nature of the software package allows you to focus on yourimmediate needs, from the computation of the resistance of a simple grid to a completesafety analysis of the complex grounding system of a substation. Simply add morecomponents as your needs evolve! TypicalAutoGrid Pro packages include:

AutoGrid Pro (Lite): This entry-level package supports any arbitrarily shaped groundingsystem buried in a uniform soil or other soil types (add-on options). It computes thegrounding system resistance and potential rise. This package is ideal for users not interestedin computing soil potentials, touch and step voltages.

AutoGrid Pro (Uniform Soil): This package analyzes any arbitrarily shaped grounding systemlocated in a uniform soil. It computes the grounding system resistance and potential rise , aswell as the earth potentials throughout any regions of interest. It also allows you to carry out afull analysis of the touch and step voltages at any location inside or outside the grid.

AutoGrid Pro (Two-Layer Soil): This package includes everything found in the Uniform Soilpackage and adds the ability to model soil structures composed of two horizontal layers. Italso adds a resistivity measurement analysis module that converts measured data into asuitable soil model.

AutoGrid Pro (Two-Layer Soil with Fault Current Distribution): This package includeseverything found in the Two-Layer Soil package and adds a powerful module whichcomputes the distribution of fault current between the grounding system and other metallicpaths such as overhead ground wires, shield wires, neutral conductors, or cable sheaths andarmours.

AutoGrid Pro (Multi-Layer Soil with Fault Current Distribution): This package includeseverything found in all other packages and adds several useful soil models, including

You no longer have to settle for substandard grounding packages because of budgetlimitations. The latest version of AutoGrid Pro enables you to select the required componentsfrom a flexible array of options such as:

AutoGrid Pro is a powerful software package for the analysis of theeffectiveness of grounding installations. It computes the resistance ofany grounding system, earth potentials anywhere inside or outside theinstallation and the ground potential rise of the grid and of nearbyburied metallic structures. It also computes the expected touch andstep voltages around the installations, and indicate the regions wheresafe limits are exceeded. It accounts for complex soil structures andfor the presence of transmission or distribution lines or cablesconnected to the grid. The computational engine of AutoGrid Pro isbased on the MALT, RESAP and FCDIST engineering modules whichhave been used in grounding studies for over twenty years. The userinterface consists of a CAD drawing module for the design of thegrounding grid, along with several integrated modules such as:

The Soil module defines the characteristics of the soil where thegrounding grid is installed. Choose a soil model from among severaltypes, including horizontally layered soils, vertically layered soils,and soils with “arbitrary heterogeneities” where the electricalproperties of the soil can vary arbitrarily as a function of position.Alternatively, specify the data obtained from soil resistivitymeasurements and let the program determine a suitable soil model.

The Circuit module is used when it is necessary to take into accountthe contribution of adjacent transmission and distribution circuits tothe grounding. Specify the geometrical locations of the neutral andphase wires and the electrical characteristics of the neutral wires, orselect these quantities from extensive conductor databases. You canalso add your own products to the databases. Alternatively, you canspecify the impedances of the wires explicitly, for a finer control. Aninput processor is available to view the circuits and theircharacteristics.

The CAD drawing module offers full 3D drawing capabilities to createthe grid. It also doubles as a central location for project management.Several tools are available to simplify the creation of complexstructures and to move, rotate, and view the grid from any angle. Usethe Object Database to quickly add commonly encountered structuresto your design, or to store your own structures.

Detailed Description

HighlightsAutoGrid Pro is a powerful, yet easy-to-use tool, which provides asimple, automated and integrated environment for carrying outgrounding studies. The software package consists of severalintegrated engineering modules that are designed to study theeffectiveness of grounding installations with respect to electricalsafety of both personnel and equipment, allowing you to suggestimprovements to existing or new installations. AutoGrid Pro supportsa wide variety of soil structures and can determine the soil structurefrom field resistivity measurements. The program can modelgrounding grids of any shape and size; several electrodes can bemodelled simultaneously. It can also determine the fault currentdistribution between the grounding system and other metallic pathssuch as overhead ground wires, shield wires, neutral conductors, orcable sheaths and armours.

The Soil module determines the characteristics of the soil fromfield resistivity measurements.The Circuit module computes the geometrical and electricalproperties of adjacent transmission or distribution lines or cablesand determines the fault current distribution.The Safety module establishes the criteria used when evaluatingsafety issues around the installation.The Report module manages the results that should be reportedor plotted.Other utility modules and tools, such as a circuit viewer and aconductor ampacity assessment tool.

To accommodate a wide range of applications, many of the program'sfeatures are optional, and can be added at any time, should the needarise.

In Summary

The Safety module lets you select the criteria that should be usedduring the safety analysis of the grounding installation. This includeslimits on touch and step voltages, based on standards of your choice(e.g., IEEE, IEC). Choose from several safety scenarios. Let theprogram decide which area should be examined for safety issues(based on the size of the grid) or draw explicitly the region of intereston top of the grid. The program reports which areas exceed the safetylimits, allowing you to quickly assess the effectiveness of correctivemeasures.

The Report module provides an exhaustive list of available plots andtext reports, whose appearance you can customize. For all computedquantities, you can choose among 2D curve plots, 3D-perspectiveplots, color intensity plots and contour plots. Plots can be produced inmost popular graphics formats.
