Grounding System Analysis in the Time Domain
XGSA_TD is a multipurpose Engineering Software for the analysis of conductors network in the time domain taking into account transients with maximum bandwidth up to about 100 MHz including Soil Resistivity Analysis and Fourier Analysis.
XGSA_TD extended the application field of XGSA_FD to the time domain.
XGSA_TD is a powerful module which extends the XGSA_FD application field to the time domain.
In this regard, XGSA_FD uses the so called “frequency domain approach”. This approach is rigorous and allows considering the frequency dependence of soil parameters.
XGSA_TD can be applied to transients with maximum bandwidth up to about 100 MHz, and then can be used for switching transients, lightning and also in fault transients in GIS.
As for XGSA_FD, also XGSA_TD is a multipurpose software and its application field includes power, grounding and lightning protection system analysis.
For instance, XGSA_TD can evaluate the distribution of the lightning stroke currents along lightning protection system (underground and overhead components) and also the related potential, electromotive force and leakage current distributions in the time domain.
XGSA_TD is also useful to calculate magnetic and electric fields due to underground or overhead electrodes in the time domain.
