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
