Probability of Concurrent Flashover in a Parallel Gap Configuration

抄録

For the analysis of back-flashover phenomena in transmission lines, accurate evaluation occurrence of flashover at the arcing horns is necessary. In this paper, parallel gap flashover phenomena are experimentally studied using real arcing horns and an impulse generator. The occurrence probability of concurrent flashover is theoretically estimated based on statistical analysis of flashover phenomena. We show that the theoretically estimated probability agrees with the experimental results.
