ARC FLASH INCIDENT DUE TO FAULTY SUBSTATION GROUND GRID
This month’s Featured Technical Paper is from the Proceedings of the 2025 International Conference of Doble Clients. The paper is titled: Arc Flash Incident Due To Faulty Substation Ground Grid.
Abstract
This paper provides an in-depth analysis of the deterioration observed in a ground grid system at an Alabama Power Company facility. Ground grids are crucial for maintaining electrical safety and operational efficiency by providing a reliable grounding system for electrical equipment. The focus of this investigation is a single ground grid that showed signs of degradation. The findings revealed critical weaknesses in the ground grid that compromised its effectiveness and posed potential risks to both equipment and personnel. The paper discusses the immediate and long-term implications of the compromised ground grid on the facility's overall electrical infrastructure. Furthermore, it outlines a detailed remediation plan, including maintenance and replacement strategies, to restore the ground grid to its optimal condition and ensure the continued safety and reliability of the electrical systems.
