The electrical behaviour of polymer insulator under different weather conditions [PDF]
, 2015 This paper presents the behavior of 33kV polymer insulator under nominal voltage and impulse by means of lightning activities. The electrical performance of the insulator is translated to electric field under uniform weather conditions which comprises of

Identification of acoustic signals of surface discharges on glass insulator under different contamination levels [PDF]
, 2011 Surface discharge is a common phenomenon that normally occurs on the insulator surface under wet contamination condition. The generation of small sparks from the surface discharge would develop many types of signals.

Natural Contamination and Surface Flashover on Silicone Rubber Surface under Haze–Fog Environment
Energies, 2017 Anti-pollution flashover of insulator is important for power systems. In recent years, haze-fog weather occurs frequently, which makes discharge occurs easily on the insulator surface and accelerates insulation aging of insulator.

Electric field and current density characteristic of contaminated solid insulator [PDF]
, 2018 The performance of an insulator may degrade over a time period. One of the main factor is due to presence of contamination on the insulator which leads to flashover, corona and damages the insulator.
