Influence of contamination distribution in characterizing the flashover phenomenon on outdoor insulator

Ain Shams Engineering Journal, 2023
The aim of this work is to model the influence of uneven contamination distribution under various humidity on the pollution flashover voltage of 11 kV porcelain insulator disc. Four scenarios of contamination distribution were proposed to test the sample

Monitoring insulator contamination level under dry condition with a microwave reflectometer [PDF]

IEEE International Conference on Properties and Applications of Dielectric Materials, 2015
—Build-up of surface contamination on high voltage insulators can lead to an increase in leakage current and partial discharge, which may eventually develop into flashover. Conventional contamination level monitoring systems based on leakage current,

Real-Time Salt Contamination Monitoring System and Method for Transmission Line Insulator Based on Artificial Intelligence

Applied Sciences
Insulators on overhead power lines have long been exposed to the outdoors and are susceptible to pollution and salt contamination. Due to factors such as wind and gravity, pollution in the atmosphere gradually deposits on the surface of the insulator. In

Flow field distribution around insulator and contamination uneven characteristic of insulator

IET Science, Measurement & Technology, 2020
The accumulation of insulator surface contamination is closely related to the distribution of flow field around the insulator. In order to study the unevenness of the insulator surface contamination, a three-unit lxy-160 insulator is selected. Based on the principle of fluid mechanics, the fluid movement state on the insulator surface is determined by ...
