Novel dc flashover model for predicting flashover voltage of the iced insulators [PDF]
High Voltage, 2021 This work first proposes a novel flashover model based on the deduced residual resistance of the ice layer. The most important finding of the field icing tests is that the double‐layer ice‐melting water film exists on the inner and outer surfaces of the ...

Anomalous flashovers of silicone rubber insulators under the artificial rain test [PDF]
Archives of Electrical Engineering, 2021 The wet flashover voltage of medium voltage insulators made of a silicone rubber is 8% lower than the wet flashover voltage of a porcelain insulator with an identical profile. These surprising results, obtained in 2012, were confirmed again in 2019.
