Zusammenfassung:Grounding rods are an important component in electrical power to protect equipment from overvoltage and current disturbances. However, corrosion can cause a significant decrease in performance and reduce system efficiency. Therefore, the diagnosis of corrosion on grounding rods is important to ensure the reliability and continuity of substation operations. In this research, a corrosion structure diagnosis was done on the grounding rod in the Belawan Port area using COMSOL Multiphysics 5.3 software. The element method is used to model the electrochemical corrosion phenomena that occur in grounding rods. Corrosion-causing factor parameters such as soil resistance, pH, temperature, humidity, and salt content are measured and evaluated. The analysis results show that there is significant corrosion on the grounding rod, especially in areas exposed to sea water and corrosive environments. The potential distribution shows uneven potential along the grounding rod. Based on this research, additional maintenance and protection measures can be proposed to reduce the risk of corrosion and extend the life of grounding rod equipment. Based on the analysis results, the input parameters differentiate electrolyte reactions which further determine grounding rod.
