XGSA_TD can be used for advanced electromagnetic interference and fields analysis of aboveground and underground systems in the time domain taking into account transients with maximum bandwidth up to about 100 MHz and is commonly used for the evaluation of interference in transient conditions. This module can also calculate the electromagnetic force on conductors.
XGSA_TD includes the tools SRA and SA for soil resistivity analysis, soil resistivity seasonal analysis and multilayer soil modelling.
XGSA_TD is highly appreciated for its power and accuracy and used by both Universities and Industries.
XGSA_TD is a powerful module which extends the XGSA_FD application field to the time domain.
In this regard, XGSA_TD 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 systems, grounding, interference and lightning 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.
