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.
This Ground Grid Design Software help engineers to visualize their substation grounding designs and decide where to locate protections and other equipment requirements.
GSA is able to analyse the performance of grounding systems of any shape with a high detail level.
Electrical data (e.g. single phase to earth fault current, data for calculation of earthing current, intervention time of protections, reference standard, etc.)
Geometrical data (e.g. grounding system layout, materials, etc.)
Physical data (e.g. soil resistivity or apparent resistivity measured values, superficial thin layer characteristics, etc.)
Decrement factor (Df) as per IEEE standard
Split factor (r) as per CENELEC standard or (Sf) as per IEEE standard
Minimum cross section of grounding system conductors for thermal specification
Double layer model soil parameters from on site measurements values of apparent resistivity
Reduction factor of touch and step voltages due to a superficial thin layer (Cs) as per IEEE standard
Maximum permissible touch and step voltages as per CENELEC and IEEE standards
Ground resistance and Ground Potential Rise values of either every grounding system or underground electrodes
Leakage current density distribution with 3D graphical representation to verify the contribution and the efficiency of grounding system portions
Ground potentials and touch and step voltages distributions on surface straight line or rectangular area by 2D or 3D coloured graphic representations, for individuation of hazardous potential areas
List of material used for grounding system (wires and rods)
Orthographic projections or isometric representations of grounding system
Possibility to choose the language (English / Spanish / German / Italian)
Finite element analysis of grounding systems of any shape, with choice of number of elementary sources to be considered
Possibility to consider more than one grounding system on the same calculation, including for instance return electrodes, transmission line grounding systems or floating potential underground electrodes
Characterization of soil as uniform or double layer model in addition with a superficial thin layer
Possibility to consider electrodes encased in concrete or buried in treated soil to lower resistivity
Libraries with typical resistivity values of soil and the most common types of surface layer materials
Possibility to export the graphic outputs to other WINDOWS® applications
