The classification of contamination levels and the drawing of contamination level distribution maps are the foundation of anti-flashover prevention work. An accurate contamination level distribution map is the basis for selecting the creepage distance of insulator outer insulation for power transmission and transformation equipment. The equivalent salt density value on the insulator surface is a quantitative data for judging the severity of the contamination condition of insulator outer insulation, and is one of the important bases for classifying contamination levels and drawing contamination zones. Therefore, the salt density measurement work is of great significance for the safe operation of the power system.
The salt density test is mainly used to evaluate the degree of contamination on the external insulation surface of GIS. By measuring the salt density value on the insulator surface, it can be determined whether the insulation performance meets the requirements. Therefore, the salt density test is necessary for GIS maintenance.
HYYM-H Insulator Equivalent Salt Density Tester is used for anti-pollution flashover detection in power systems. It is a dedicated measuring instrument for measuring the equivalent salt density on the surface of insulators (hereinafter referred to as "salt density"). At the same time, it can also measure the conductivity and temperature of the solution. The entire machine is widely applied in the fields of power, teaching, research, and other related industries due to its high measurement accuracy, wide measurement range, and convenient use.
