Tower grounding device provides the discharging channel for fault currents, ensuring the safe and reliable operation of transmission lines. However, the carbon steel tower grounding device is prone to corrosion, which affects the discharging performance and causes potential safety hazards. Existing evaluation methods are divided into subjective evaluation through excavating grounding device and objective evaluation through experimental detection. However, these methods suffer from poor accuracy in the evaluation results. In order to solve the above-mentioned problems, this paper proposed a comprehensive evaluation method for corrosivity of grounding device based on fuzzy theory, taking soil resistivity, PH value, water content and salt content as evaluation factors, and integrating subjective and objective weights based on game theory, which realizes complementary advantages of subjective and objective methods. Finally, a comprehensive evaluation algorithm for the grounding device corrosion is formed. Experiments are conducted to validate the effectiveness and accuracy of the proposed method.
