COMPARATIVE STUDY ON ICING STATE AND AC FLASHOVER PERFORMANCE BETWEEN COMPOSITE INSULAORS UNDER ENERGIZED AND NON-ENERGIZED ICING CONDITION
To find out the difference of icing states and flashover performance between energized and non-energized icing of composite insulators, icing tests with and without voltage applied on two kinds of composite insulators were accomplished in the artificial climate chamber. It was found that, compared to non-energized icing, less ice accreted on energized insulator with smaller density which could be altered by icing water conductivity, and considerable difference of flashover performance existed between the iced insulators under energized and non-energized icing conditions. Thus, icing tests with composite insulators energized is preferred.
