| چکیده | ||
| Grounding systems play a crucial role in ensuring the safety and reliability of high-voltage substations. However, variations in soil composition, particularly the presence of heterogeneous layers such as rock, can significantly impact grounding effectiveness. This study investigates the effects of non-homogeneous soil on step and touch voltage patterns using the Finite Element Method (FEM) in COMSOL Multiphysics. The simulation compares grounding performance in homogeneous and heterogeneous soils, analyzing electric potential and field distribution. A sensitivity analysis is conducted to assess the impact of varying soil resistivity on grounding safety. Additionally, different grounding techniques are compared to identify optimal solutions for mitigating potential hazards. The results indicate that heterogeneous soils increase step voltage and potential gradients, posing higher risks for personnel and equipment. The findings provide essential insights for improving grounding system designs in complex soil environments and expands new technical horizons to accurate investigation of new enhanced grounding grid structures. | ||
