Abstract:
The flashover performance of polluted insulators in high-voltage transmission systems is critically influenced by multiple factors, including leakage current, surface conductivity, creepage distance, and contamination severity. This study investigates the interplay between these parameters through Mathematical model using the leakage current of the polluted insulator to predict the voltage flashover. The results demonstrate that Flashover voltage exhibits an inverse exponential relationship with leakage current, showing a reduction in flashover as leakage current increases. The study further compared the mathematical model results with the experimental results. The results shows over 90% correlation between the mathematical prediction model with experimental test results The mathematical model based approach can be utilized to predict the voltage flashover characteristics of sea salt polluted insulators.
