Abstract:The discharge and flashover phenomenon of post insulators in rainy weather has not been given sufficient consideration; however, with the construction of ultra-high voltage power grids, the performance of the external insulation and the ability to withstand special climate conditions need to be guaranteed. Therefore, it is meaningful to conduct studies on the discharge characteristics of contaminated post insulators under rainfall conditions. Moreover, the conventional perception tends to confuse the flashover… Show more
In the modern sense, DC transmission involves converting three-phase AC into stable DC at a converter station, then transmitting it over DC transmission lines to another converter station, where it is inverted back into three-phase AC [...]
