XGSLab

XGSLab (Over and Under Ground System Laboratory) is one of the most powerful software packages for grounding system analysis, electromagnetic fields, interference and lightning analysis and the only software on the market that takes into account both EN and IEEE Standards.

XGSLab includes the modules:

All modules are integrated in an “all-in-one” package and based on a hybrid calculation method (or “PEEC” method) which considers transmission line, circuit and electromagnetic theory combined into a single calculation model.

Hybrid methods combine the strengths of other methods and are well suited for engineering purposes because they allow the analysis of complex scenarios including external parameters such as voltages, currents and impedances. For these reasons, XGSLab can be considered a real laboratory.

Video - An Introduction to Grounding Calculations and Why They Are Necessary

 
This video is a recording of a webinar, given by Michael Antonishen, P.E. at TriAxis, a Division of DEA, and provides a basic introduction to grounding safety calculations (IEEE 80 step & touch) that are generally performed for medium and high voltage AC power stations or similar facilities. Basic grounding concepts and calculation inputs are introduced, and the need for this type of modeling and analysis is discussed.

Applications

The following table summarizes the main applications of the available models.

Application GSA GSA_FD XGSA_FD
Grounding (small systems) Yes Yes Yes
Grounding (large systems) No Yes Yes
Cathodic Protection Systems No Yes Yes
Magnetic Field No Yes Yes
Electric Field No No Yes
Electromagnetic Interferences No Yes Yes
Fault Current Distribution No No Yes
Lightning effects for a single frequency No No Yes

XGSA_TD can be applied to analyze in the time domain, current and potential distribution on underground and overhead conductor networks energized by means current or voltage transients. It can calculate the consequent distributions of earth surface potentials and electric and magnetic fields.

Product Details

GSA (Grounding System Analysis)

GSA_FD (Grounding System Analysis in the Frequency Domain)

XGSA_FD (Over and Under Ground System Analysis in the Frequency Domain)

XGSA_TD (Over and Under Ground System Analysis in the Time Domain)

XGSA_TD Is a completely new module that extends the XGSA_FD application field to the time domain.

In this regard, XGSA_FD uses the so called “frequency domain approach.” As known, a transient can be considered as the superposition of many single-frequency waveforms calculated with the forward Fourier transform.

Using the frequency domain model implemented in XGSA_FD, it is then possible calculate a response for each of these single frequency waveforms.

The resulting time domain response can be obtained by applying the inverse Fourier transform to all these responses.
