Software for Grounding System Analysis

GSA is a computation code for substation grounding grid design and analysis of low frequency grounding systems developed by SINT Informatica Srl. GSA considers both European standard CENELEC (European countries: EN 61936-1:2010 and EN 50522:2010) and American standard IEEE Std 80™-2000.

This Ground Grid Design Software help engineers to visualize their substation grounding designs and decide where to locate protections and other equipment requirements.

 

   VIDEO TUTORIAL

 Note: GSA is a GSLab Module.

 

GSA is able to analyse the performance of grounding systems of any shape with a high detail level.
The numerical and graphical input data, the optimised and validated computation algorithms and powerful graphical facilities render GSA an indispensable tool for grounding system design and verification.
In the next future GSA will be part of the NEPLAN® power system analysis software.

INPUT DATA

grounding  system software Electrical data (e.g. single phase to earth fault current, data for calculation of earthing current, intervention time of protections, reference standard, etc.)
grounding  system software Geometrical data (e.g. grounding system layout, materials, etc.)
