Abstract :
The importance of the research on insulator pollution has been increased considerably with the rise of the voltage of transmission lines. In order to determine the flashover behavior of polluted high voltage insulators and to identify to physical mechanisms that govern this phenomenon, the researchers have been brought to establish a modeling. In this study after presenting the theoretical and experimental open model, a dynamic arc model has been developed to calculate the flashover. The validity of the model was verified by comparing the computed results with the experimental results of previous researchers and good correlation has been shown.
