Eficacia de redes de puesta a tierra de dos capas en subestaciones GIS de alta tensión y consideraciones de diseño mediante FEM

With the rising demand for electricity and the expansion of power generation facilities, grounding systems have become critical for ensuring human safety and equipment protection. This study employs the finite element method to model single- and double-layer grounding networks, evaluating their effectiveness in mitigating step and touch voltages. Findings reveal that, despite increased complexity and cost, the double-layer configuration does not significantly enhance ground resistance reduction or voltage distribution, indicating that the single-layer network remains a reliable and efficient solution.
