XGSA_TD is a multipurpose Engineering Software for the analysis of conductors network in the time domain taking into account transients with maximum bandwidth lower than a few MHz including Soil Analysis.

XGSA_TD uses the “frequency domain approach” and uses XGSA_FD as solver. Then also XGSA_TD can take into account both underground and overhead conductors network.

 

 

GENERAL DESCRIPTION

XGSA_TD is a computation code for the analysis of underground and/or overhead conductors network in the time domain taking into account transients with maximum bandwidth lower than a few MHz.

XGSA_TD uses the “frequency domain approach” and the XGSA_FD module as solver. Then XGSA_TD extends the XGSA_FD application field to time domain.

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 field due to underground or overhead electrodes in the time domain.
