Direct-reading Salt Density Tester
The Direct-reading Salt Density Tester is used for anti-pollution flashover detection in power systems. It is a measuring instrument for the equivalent salt deposit density (ESDD) on the surface of insulators, and can also measure the conductivity and temperature of the solution. With its high measurement accuracy, wide measurement range, and ease of use, the instrument is widely applied in electric power, education, scientific research, and other related industries.
The classification of pollution levels and the drawing of pollution level distribution maps are the foundation of anti-pollution flashover work. An accurate pollution level distribution map is the basis for selecting the external insulation creepage distance of porcelain insulators for transmission and transformation equipment. The equivalent salt deposit density value on the insulator surface is quantitative data for judging the severity of external insulation pollution, and it is the basis for classifying pollution levels and drawing pollution area maps. Therefore, salt density measurement is of great significance to the safe operation of power systems.
