Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a method and a device for measuring the pollution and salt density on the surface of an insulator. Background technique [0002] With the improvement of the operating voltage of the power system and the expansion of the power grid, more and more insulators are used for line insulation. Because line insulators are exposed to the air for a long time, it is easy to deposit dirt on its surface. The dirt contains electrolytic substances. Under humid weather conditions such as fog, dew, and drizzle, the electric strength of the insulator is greatly reduced, and the external insulation of the power system may be damaged. Under the action of overvoltage, a flashover occurs, causing a power outage and endangering the normal operation of the power system. [0003] The high-voltage insulator pollution test uses some test methods to obtain the pollution withstand voltage of ...
