【Abstract】 Based on the results of DC flashover test carried out on iced XZP 160 insulators in the artificial climate chamber, this paper puts forward the test method of the average flashover voltage of iced DC insulator, and analyzes the effect of altitude on DC flashover voltage of iced insulator. And the relations between DC flashover voltage of iced insulator in high altitude or low atmospheric pressure and ice amount accreted on insulators have been analyzed and a voltage correction method of iced DC insulator at low atmospheric pressure condition is puts forward.更多还原
