Introduction to the most awaited module of XGSlab "NETS"

NETS is a very flexible tool to solve full meshed multi conductors networks and is based on the n-phases system representation.

This approach is general and overcome the classic method of symmetrical components and can be used to represents power systems as multiconductors networks enabling the consideration of asymmetrical systems also in presence of grounding circuits or circuits with a different phases number.

The network components (generators, lines, cables, transformers, loads ..) are represented with n-ports cells and the connection between cells is obtained by means of n-ports buses.

NETS can be used to solve networks in steady state or fault conditions and to calculate voltages and currents or short circuit currents (three phase, phase to phase, phase to phase to earth, single phase to earth) with or without fault impedances.

In particular, NETS can be used for the calculation of the fault current distribution.

NETS is then a very useful tools to calculate data input for others XGSLab modules (for instance the split factor or the current to earth) and represents the link between XGSLab and the commercial software for power systems analysis.

Introduction to XGSlab Grounding design software

ELECTROMAGNETIC SIMULATION FOR POWER, GROUNDING AND LIGHTNING PROTECTION SYSTEMS

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

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
The new module NETS (Network Solver) is in progress

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