Key Features

XGSLab is packed with powerful features designed to streamline the analysis of electromagnetic phenomena. Its modular structure allows engineers to select the tools they need for specific projects.

Core Modules and Analysis Capabilities

The XGSLab software suite comprises six primary analysis modules, integrating into a single, powerful package .

• GSA (Grounding System Analysis): The foundational module for designing and analyzing grounding systems. It includes tools for soil resistivity analysis (SRA), seasonal soil analysis (SSA), and conductor sizing. This module calculates critical safety parameters like grid resistance, touch and step voltages, and provides automated reporting .

• GSA_FD (Frequency Domain Grounding System Analysis): An advanced module that builds on GSA by computing frequency-dependent self and mutual impedances of conductors. It uses the full-wave PEEC (Partial Element Equivalent Circuit) numerical model to handle complex grounding systems in large power facilities and substations, ensuring compliance with IEEE and other international standards .

• XGSA_FD (Frequency Domain System Analysis): This module is designed for comprehensive electromagnetic interference (EMI) and electromagnetic field (EMF) analysis. It can model complex infrastructure projects, evaluating capacitive, inductive, and conductive interference on pipelines, railroads, and communication cables in shared corridors, all based on the full-wave PEEC model .

• XGSA_TD (Time Domain System Analysis): Essential for analyzing transient events such as lightning strikes, switching surges, and faults in Gas Insulated Substations (GIS). By utilizing the Inverse Fast Fourier Transform (IFFT), this module provides critical insights into transient behavior, covering frequencies from DC up to about 100 MHz .

• NETS (Network Solver): A specialized module for detailed fault current distribution calculations. Unlike standard methods, NETS uses the phase components method and graph theory to provide highly accurate, assumption-free results for current division, surpassing the capabilities of traditional sequence component methods .

• SHIELD/SHIELD_A (Lightning Shielding Analysis): These modules are based on a complete 3D geometric model. They allow engineers to design lightning protection systems using the most widely accepted methods, such as the Rolling Sphere and Eriksson methods, ensuring the safety of infrastructure against direct lightning strikes .

Technical Specifications and Data Management

XGSLab excels in its technical capabilities and data integration.

• Wide Frequency Range: Applicable from DC to about 100 MHz, covering all power system frequencies and the significant spectrum of electromagnetic transients .

• Advanced Soil Modeling: Supports uniform, multilayer, and multi-zone soil models, which are critical for accurately predicting grounding system performance .

• Parallel Computing: Leverages parallel computation and advanced mathematical libraries for fast and efficient processing of complex models .

• Open and Interoperable Workflows: Data can be imported from and exported to AutoCAD® (DXF/DWG) . Numerical outputs are readable by MATLAB®, Microsoft EXCEL®, and Google Earth® (KML/KMZ) . Frequency-dependent impedances can be exported to EMTP® or ATP® for dynamic behavior studies .

What’s New in the Latest Version

The XGSLab V2025.1.9 release focuses on refining the user experience, enhancing computational efficiency, and updating compliance with the latest international standards. Key improvements include:

• Enhanced Solver Performance: Optimizations to the RAM Saving threshold further improve the efficiency of large-scale simulations, particularly for complex models with tens of thousands of elements .

• Extended Compliance: Continuous updates to ensure full compliance with the latest editions of international standards, including IEC/TS 60479-1, EN 50522, and IEEE Std 80 for touch and step voltage limits, and IEC 62305-3 and IEEE Std 998 for lightning shielding .

• Streamlined Workflows: Further integration across the XGSLab suite provides a more seamless all-in-one package for engineers, reducing the learning curve and increasing productivity for both novice and experienced users .
