Influence of tower anticorrosion coating as contaminant on operation characteristics of composite insulator

open access: yesHigh Voltage, 2018
Anticorrosion coatings are commonly applied to prevent rust-based corrosion in transmission towers. Unfortunately, anticorrosion coatings may drip onto the surface of composite insulators during the construction process, which is likely to do harm to ...

Dry band formation mechanism of composite insulator with generalized finite difference-time domain

open access: yes电力工程技术, 2022
The pollution flashover of composite insulators is mainly the flashover caused by alternate occurrence of arc development and dry band formation. At present, researchers have investigated the development of insulator arc along the surface.
