XGSLab is one of the most powerful software of electromagnetic simulation for power, grounding and lightning protection systemsand the only software on the market that takes into account IEC, EN and IEEE Standards in grounding system analysis.

Strength points:

      • EASY: A program with an intuitive interface. Very easy even for beginners. Users expert with competitors tools can directly use XGS.
      • WORLDWIDE: The only software in the market that takes into account International (IEC), European (EN) and USA (IEEE) standards.
      • VALIDATED: Frequency dependent self and mutual impedances can be exported to EMTP® in order to simulate the dynamic behavior of large grounding systems during electromagnetic transients.
      • COMPLETE: A complete tool for the simulation of Power, Grounding and Lightning Systems.
      • POWERFUL: Based on a general approach and then suitable for many applications, in a wide frequency range, with arbitrary conductors network and many soil models including multilayer.
      • EMTP®: Accuracy validated since 1990 by comparison with results from analytical cases, published research, field measurements, and similar programs.

XGSLab includes the modules:

      • GSA (GROUNDING SYSTEM ANALYSIS) for basic application with underground systems
      • GSA_FD (GROUNDING SYSTEM ANALYSIS in the FREQUENCY DOMAIN) for general applications with underground systems
      • XGSA_FD (OVER AND UNDERGROUND SYSTEM ANALYSIS in the FREQUENCY DOMAIN) for general applications with overhead and underground systems
      • XGSA_TD (OVER AND UNDERGROUND SYSTEM ANALYSIS in the TIME DOMAIN) for general applications with overhead and underground systems
      • NETS (NETWORK SOLVER) to solve full meshed multiconductors networks

XGSLab integrates the module SRA (SOIL RESISTIVITY ANALYSIS) and XGSA_TD integrates also the module FA (FOURIER ANALISYS direct / inverse).

The XGSLab application field is so wide because the implemented model is for general use and solves the Maxwell equations in non stationary conditions taking into account the earth lack of homogeneity by the Green functions, the earth reaction by the Sommerfeld integrals and moving from the frequency to the time domain by means the Fourier transforms.

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 join the strong points of the 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.

All algorithms implemented in XGSLab are highly efficient in terms of computation speed and has been validated and tested by many Customers in the world.

XGSLab is easy to use by engineers who need not to be necessarily experts in the specific field, and moreover accurate, stable and fast.  


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) Yes Yes
Cathodic Protection Systems Yes Yes
Magnetic Field Yes Yes
Electric Field Yes
Electromagnetic Interferences Yes Yes
Fault Current Distribution Yes
Lightning effects for a single frequency Yes


XGSA_TD can be applied in order to analyse in the time domain current and potential distribution on underground and/or overhead conductors network energized by means current or voltage transient and can calculate the consequent distributions of earth surface potentials and electric and magnetic fields.

NETS is a tool based on circuit theory and then it is completely different form the other modules XGSLab modules based on the electromagnetic fields theory.
NETS can solve full meshed multi-conductor and multi-phase networks composed of multi-port cells connected by means of multi-port buses.
NETS can calculate potentials and currents in all ports in steady state or fault conditions and in particular can be used for the calculation of the fault current distribution in power networks.




A complete tool for the simulation of  Power, Grounding and Lightning Systems.

while the application limits for overhead systems can be assumed from DC to 100 MHz.
