Abstrakt: For the analysis of back‐flashover phenomena of transmission lines, accurate evaluation of flashover occurrence at arcing horns is necessary. In this paper, parallel gap flashover phenomena are studied theoretically in the following conditions: (i) the gap lengths are different, and (ii) after one of the gaps flashes overs, there remains some residual voltage. The formulae for the occurrence probabilities of concurrent flashover on these conditions are introduced. Based on the analysis, application to the analysis of multiphase flashover is discussed. © 2018 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc. [ABSTRACT FROM AUTHOR]
