“…A grounding grid is an important device used in substations for work grounding, lightning grounding, and protective grounding, to ensure the safety of people, equipment, and systems [1][2][3]. In the case of a lightning strike or power system failure that releases a large amount of current to the ground, the grounding grid plays a role in quickly dissipating the current and reducing the contact voltage and step voltage [4,5].…”

The corrosion of grounding grid materials in soil is a prominent factor in power and electrical equipment failure. This paper aims to delve into the corrosion characteristics of grounding grid materials and the corresponding methods of safeguarding against this phenomenon. Firstly, the influencing factors of the soil environment on the corrosion of the grounding grid are introduced, including soil physicochemical properties, microorganisms, and stray currents. Then, the corrosion behavior and durability of common grounding grid materials such as copper, carbon steel, and galvanized steel are discussed in detail and compared comprehensively. In addition, commonly used protective measures in China and outside China, including anti-corrosion coatings, electrochemical protection, and other technologies are introduced. Finally, it summarizes the current research progress and potential future directions of this field of study.
