Product Introduction
Wuhan UHV Power Technology Co.,Ltd., is a professional manufacturer and supplier of high-voltage power testing equipment in China.The Intelligent Conductivity Salt Density Tester is a specialized instrument designed to measure the equivalent salt deposit density (ESDD) on insulator surfaces, as well as the conductivity and temperature of the solution. It is primarily used for anti-pollution flashover testing in power systems. With high measurement accuracy, a wide measurement range, and convenient operation, the instrument is widely applied in electric power, education, scientific research, and other related industries.
The classification of pollution levels and the development of pollution zone maps are fundamental to anti-pollution flashover work. Accurate pollution zone mapping is essential for selecting the appropriate external insulation creepage distance for electrical porcelain used in power transmission and transformation equipment. The equivalent salt deposit density on insulator surfaces serves as a quantitative indicator for assessing the severity of insulation pollution on electrical porcelain and is a key basis for pollution level classification and pollution zone mapping. Therefore, salt density measurement is of great significance to the safe operation of power systems.

FAQ about Conductance Salt Density Tester
Q: Why is it necessary to measure insulator salt density?
A: Salt and other contaminants on the insulator surface can form a conductive layer when damp, reducing insulation performance and increasing the risk of pollution flashover. Salt density measurement can provide data support for pollution flashover risk assessment, equipment cleaning, and anti-pollution flashover measures.
Q: Can the test results be used for power equipment maintenance decision-making?
A: Yes. After accumulating salt density measurement data over time, contamination trends across different equipment and areas can be analyzed, providing data support for insulator cleaning schedules, inspection frequency, and anti-pollution flashover measures.
Q: Are the test results of the Conductance Salt Density Tester stable?
A: The device uses conductivity measurement to detect the contamination solution and incorporates temperature compensation calculations to determine equivalent salt density, which reduces the impact of ambient temperature changes on test results, making it suitable for both on-site and laboratory testing.
