XGSA_FD is a multipurpose Engineering Software for Grounding Systems, Electromagnetic Field and Interference Analysis in the frequency domain from DC to about 100 MHz including Soil Resistivity Analysis.
XGSA_FD extended the application field of GSA_FD to overhead systems.
GENERAL DESCRIPTION
XGSA_FD extends the GSA_FD application field to the overhead systems.
Also XGSA_FD is based on a PEEC full wave numerical model and can be applied in general conditions with same conductors and in the same frequency range of GSA_FD.
Using screened conductors XGSA_FD can simulate gas insulated systems like GIS and GIL.
XGSA_FD can also manage catenary conductors and bundle conductors too (solid, hollow or stranded and coated or bare) and can take into account sources where potential or leakage current and longitudinal current are forced and independent by other conditions.
XGSA_FD is a multipurpose software and its use is not limited to specific cases. XGSA_FD application field includes grounding system analysis but is oriented in particular way to solve electromagnetic compatibility or interference problems due to resistive, capacitive and inductive coupling in air or in the earth.
For instance, XGSA_FD can evaluate electromagnetic interferences between overhead or underground power lines and installation as pipelines, railways or communications lines.
XGSA_FD is also useful to calculate magnetic and electric fields due to underground or overhead electrodes (grounding systems, buried cables, overhead power lines) and can be used to investigate the effectiveness of passive loop mitigation systems.
Moreover, XGSA_FD integrates a powerful tool based on the model suggested by CIGRE for the evaluation of the corona effects (power losses and radiofrequency interferences).
