Preliminary study on icing and flashover characteristics of inverted T-type insulator strings

Influence of snow accretion on arc flashover gradient for various types of insulators

“…To analyse the electrical performance of insulators with different structural configurations and leakage distances, the arc flashover gradient, which represents the flashover voltage on the per-unit leakage distance of insulators, is used to describe the electrical properties of snow-covered insulators [16,26,27]:…”

“…Extensive researches on the performance of insulators at home and abroad have been conducted. Numerous and significant achievements have been made in using nanoparticles to improve the electrical field characteristics [10][11][12][13], icing formation mechanism [4,14], icing monitoring [7,15] and ice flashover of insulators [16,17]. However, relatively few studies have focused on the performance of snow-covered insulators.…”

Dynamic Simulation of Power Systems Considering Transmission Lines Icing and Insulators Flashover in Extreme Weather

“…In [13] and [14], the arc development process of glaze ice-covered insulators and the effect of ice shedding on the discharge characteristics were analyzed in an AC flashover scenario. The flashover characteristics for different insulators are also different, which were discussed in [15] and [16]. Further research on ice flashover was conducted based on the above mechanistic analysis.…”
