In this paper, a dynamic model that computes the flashover voltages of polluted insulators energized with dc voltage is presented. The salient feature of this model is that it takes into account the configuration of the insulator profile at every instant, which plays an important role in the flashover process of the dc polluted insulators. A number of practical insulator geometries have been studied to demonstrate the model. 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.
