In order to establish a method for monitoring whether flashover occurs or not in a string of
insulators based on leakage current waveforms and their frequency characteristics, the …

The paper presents the results of using the fundamental and the low frequency harmonic
components of leakage current to study aging of silicone rubber in salt-fog. Experiments …

This paper presents investigations on the performance of 33 kV silicone rubber insulators
characterized by different creepage lengths, which aimed to find out whether the insulators …

Polymers are ever more widely and more prominently used in microelectromechanical
systems. They provide significant added value to the existing silicon-based technologies …

Ultraviolet (UV) radiation decreases the hydrophobicity of silicone rubber (SiR) insulators.
Lack of hydrophobicity on the surface of such insulators lowers the flashover voltage and …

Leakage current produced on contaminated ceramic and polymeric insulating surfaces was
analyzed using a wavelet transform technique providing time-frequency domain information …

Flashover of contaminated insulators in polluted areas is one of the most important factors
influencing the operation of transmission and distribution lines and substations. Hence …

In order to assess how severe the contamination level of the surface of power line insulators
and to prevent unpredictable contamination flashovers, it is important to seek optimal …

Ceramic insulators, specifically porcelain and glass insulators, have widely been used all
over the world since the 19th century [1, 2]. However, when such insulators are energized …

This paper reports an investigation into the leakage current harmonic components of 45
units of glass insulator samples. The insulator units comprise 5 groups of insulators: new …
