Effects of the External Series Impedance on Concurrent Flashover Probability in a Parallel Gap Configuration

Abstract

Accurate evaluation of flashover occurrence at arcing horns is necessary for the analysis of multiple back-flashover phenomena of transmission lines. In this paper, analyzed results of flashover phenomena in parallel gap configuration with residual voltage after flashover at one of the gaps are compared with experiments. The agreement between the theory and experiments is fairly well, which proves the validity of the analysis.
