Probability Calculation of Pollution Flashover on Insulators and Analysis of Environmental Factors
IEEE Transactions on Power Delivery, 2021Insulator pollution flashover occurs frequently and is harmful to the power transmission and distribution network. But the randomness of the pollution flashover and the complex influencing factors make it difficult to be predicted.

Atmospheric Research, 1998
The main objective of the present study is to further our understanding of the influence of ambient temperature, freezing water conductivity and nature of applied voltage on the surface flashover of ice. Flashover tests were carried out using two metallic hemispherical capped rods 12 mm in diameter, separated by an ice surface. The distance between the

Pollution deposition along with ultraviolet (UV) radiation and electro-thermal stress cause the composite insulators to face with critical conditions. The type of pollution which settles on insulators is not only uniform but also it can be non-uniform ...

In surface science, when a high voltage is applied, a penetrating discharge occurs along the gas-solid interface, which is called surface flashover. Although the electron stimulated gas desorption is a crucial process for surface flashover in vacuum, the

2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013
Atmospheric ice accretion, combined with pollution, has been identified as a significant risk factor in the reliability of line and station insulators in cold climate regions. Flashovers occurring on ice- and snow-covered insulators result from combinations of a number of factors.

Proceedings of the Institution of Electrical Engineers, 1968
This paper presents a review of published work on flashover, mainly of Russian, German and American origin. The information obtained from these sources, combined with supporting experimental work, enables a comprehensive explanation of the phenomena to be given. A list of running conditions for which flashover has been reported is given.

Flashover surface spectrometry
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1972, 1972A bakeable, ultrahigh vacuum, time-of-flight mass spectrometer has been constructed in order to investigate, for the first time, the nature of the ion species formed prior to the flashover of a parallel plate diode.1 During operation, the field in the gap of the diode is maintained approximately 5% below that required for visible flashover.

Parallel Multigap Flashover Probability
IEEE Transactions on Power Apparatus and Systems, 1969This study aims to make clear the air-gap flashover probabilities for positive long-front impulse voltages, especially in the extremely small probability domain, by using the flashover characteristics of the parallel multigap, which consists of 20 3- meter rod-rod gap pairs.
