Insulator dirtiness, refers to the insulator is located in a certain geographical area of the degree of filth, in the long-term operation process, the insulator surface is prone to accumulate dust, sand particles, bird droppings, insect carcasses, salt spray and other filth, in the humid environment, the soluble substances in the filth gradually dissolved in water, will form a layer of conductive film on the insulating surface, so that the level of insulation of the insulator is greatly reduced, which in turn triggers flashover accidents which threatens the safety of the power grid. Therefore, it is necessary to carry out regular dirt detection and cleaning of insulators.

By measuring the equivalent salt density and gray density of the dirt on the insulator surface, the composition and concentration of the dirt can be understood, so as to determine the degree of its influence on the performance of the insulator.

Shenzhen Dingxin Wisdom Technology Co., Ltd.'s transmission line absolute Rim Filth Online Monitoring DeviceDX-WPS100- WH, based on optical detection technology, can accurately calculate the salt density and gray density of insulator surface by detecting changes in light energy parameters and changes in ambient temperature and humidity, and wirelessly sends the monitoring data to the user's information platform, which helps to detect potential safety hazards in a timely manner and provides a basis for taking corresponding cleaning or maintenance measures to ensure stable operation of the power system.

Insulator dirtiness measurement is one of the important means to evaluate the performance of insulators. By replacing manual monitoring points with transmission line insulator dirtiness on-line monitoring devices, we can realize the intelligent anti-fouling management of transmission line insulators, which is widely used in industrial zones, mining zones, sandy and dusty zones, and other areas with high pollution and high humidity.
