EYHM Grey Density Tester

1、 Product Overview

In the power grid system, substations and transmission lines with high voltage levels and large transmission capacity play an important role. In the areas where transmission lines pass through, industrial pollution, salt spray from sea breeze, dust in the air, and other pollutants gradually accumulate and adhere to the surface of insulators, easily forming a pollution layer. Due to the greatly reduced insulation strength of polluted insulators, they can cause flashover under normal operating voltage, resulting in large-scale power outages and pollution flashover accidents.

Due to the contamination on the surface of insulators containing both soluble and insoluble components, including ash density（NSDD）It refers to the ratio of insoluble components in the surface layer pollution of insulators to the surface area, which is different from the soluble components in pollution (measured by equivalent salt density)ESDDDue to the relationship between salt density and ash density in the degree of pollution5—10Multiple dispersion,Insulators with the same equivalent salt density but different ash densities may be at different pollution levels, thereforeThe confirmation of pollution level requires a combination of equivalent salt density and ash density, and only by conducting ash density measurements can the pollution level be accurately determined.
