GSA FD is an Engineering Software for Earth Grid Calculations and Design in the frequency domain 0 - 1 MHz including Soil Analysis.
GSA considers both American (IEEE) and European (EN) standards and it is useful in all cases when the equipotential condition of the electrode is not fulfilled.
That is to say with a large grounding system or low soil resistivity or high frequency.
GSA FD can consider both resistive and inductive coupling.
GSA FD is a computation code for design and analysis of grounding systems in the frequency domain 0 - 1 MHz, developed by SINT Ingegneria Srl. GSA FD considers both European standards (EN 61936-1:2010 and EN 50522:2010) and American standard (IEEE Std 80™-2000).
GSA FD is able to analyse the frequency domain performance of extensive earthing systems composed of more distinct electrodes of any shape with a high detail level. The graphical (from AutoCAD ® “dxf” files) and numerical input data, the optimised and validated computation algorithms, the powerful graphical facilities render GSA FD an indispensable tool for grounding system design and verification, when the longitudinal impedance of the conductors are significant.
Moreover, GSA FD considers both resistive and inductive coupling between conductors.
GSA FD includes a module to calculate uniform or double layer soil equivalent models starting from measured soil resistivity data.
The buried electrodes can be realized with solid or hollow and coated or bare conductors connected in arbitrary way.
GSA_FD is one of the most powerful and general software on the market for grounding system analysis and can be used to solve electromagnetic compatibility or interference problems due to resistive, capacitive and inductive coupling in the earth or cathodic protection problems involving extensive coated and uncoated buried structure.
GSA_FD is also useful to calculate magnetic field due to grounding systems or buried cables and can be used to investigate the effectiveness of passive loop mitigation systems.
