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

Monitoring contamination level on insulator materials under dry condition with a microwave reflectometer [PDF]
, 2016 Current techniques used for monitoring the levels of contamination on high voltage insulators, such as leakage current and infrared, are not effective in dry conditions since they require the surface of the insulator to be wetted by fog, rain or snow. If
