| Abstract: | In this paper, laboratory investigations of discharg e processes and flashover performances under the different climate condition simul ated in the artificial climate chamber are carried out on XZP-160 porcelain ins ulator, FC160P/C170DC glass insulator and 10 kV DC composite insulator. Based on the laboratory investigations, it analyzes the relation between the DC flashove r voltage of the different kinds of iced insulators and the effect of voltage po larity. Test results indicate that the iced porcelain insulator and the iced gla ss insulator have evident effect of polarity, and that the effect of polarity of the composite insulator depends on ice status. |
