XGSLab

XGSLab is one of the most powerful software for electromagnetic simulation for power, grounding and lightning protection systems and the only software on the market that takes into account International (IEC/TS 60479-1:2005), European (EN 50522:2010) and American (IEEE Std 80-2000 and IEEE Std 80-2013) Standards in grounding system analysis.

New XGSLab 9.5.1 Product Update

The engineers at SINT Srl in Italy have recently released version 9.5.1 of XGSLab, with multiple additions and enhancements that make the software more powerful, versatile, and easier to use. Here are some of the major enhancements in the latest upgrade:

  

Seasonal Analysis
Implemented the new Seasonal Analysis tool, which considers the effects of seasonal temperature on the resistivity of the soil model. Users can evaluate their designs to verify compliance is met spring, summer, fall, and winter. Watch a video expaining this feature here.

Google Earth Integration
Google Earth Exportation lets you use 3D system layout and many calculation results to see your project in the world.

Faster 3D Image Generation
3D picture generation is faster and includes two tiers of quality:

Why XGSLab

XGSLab Module Options

All modules are integrated in an “all-in-one” package, 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/equipotential systems) Yes Yes Yes
Grounding (large/general 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 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.

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. It 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.

Product Details

GSA (Grounding System Analysis)

GSA is a widely utilized and recognized module for earth grid calculations and design including soil analysis.

XGSLab GSA Tutorial Video - A Grounding System Analysis Applying the EN 50522 Standard

This video follows the XGSLab tutorial documentation for the GSA module incorporating the EN 50522 standard. In the tutorial, a substation grounding system is subjected to a fault resulting in a ground/earth potential rise at the grounding system. We also model an adjacent tank buried in the earth that is a recipient of voltages transferred through the soil. In the video we use the Soil Resistivity Analyzer to determine a soil model from Wenner resistivity measurements, then proceed to import our grounding systems for the substation and the buried tank from an existing DXF. The fault current split tool is used to calculate the fault split, reducing the total fault contributing to the ground/earth potential rise. Safety plots are generated based on the permissible touch and step voltage limits with regard to EN 50522 standard.

GSA_FD (Grounding System Analysis in the Frequency Domain)

GSA_FD is a module for earth grid calculation and design in the frequency domain, including soil resistivity analysis and represents the state of the art of grounding software.

XGSLab GSA_FD Tutorial Video - A Grounding System Analysis Applying IEEE Std 80

This video follows the XGSLab tutorial documentation for the GSA_FD module incorporating the IEEE Std 80-2013. In the tutorial, a substation grounding system is subjected to a fault and transfers the ground/earth potential rise to the connected steel factory grounding system. In the video we use the Soil Resistivity Analyzer to determine a soil model from Wenner resistivity measurements, then proceed to import our grounding systems for the substation, steel factory, and adjacent site entrance from an existing DXF. The fault current split tool is used to quickly determine fault split calculation, reducing the total fault contributing to the ground/earth potential rise. 

XGSA_FD (Above and Below Ground System Analysis in the Frequency Domain)

XGSA_FD extends the GSA_FD application field to the overhead systems.

XGSA_TD (Above and Below Ground System Analysis in the Time Domain)

XGSA_TD is a powerful module which extends the XGSA_FD application field to the time domain.

NETS (Network Solver)

NETS is a very flexible tool able to solve full meshed multi-conductor and multi-phase networks taking into account all the neutral conductors paths as well as the earth path.
