Behavior of Insoluble Materials in Artificial Contamination Tests

Zusammenfassung
It was reported that the de flashover voltage under an artificial contamination test
sometimes was affected considerably by the type of insoluble materials in the contaminant.
To clarify the cause of this phenomenon, the physical characteristics of
some contamination slurries and the conductivity of the artificially contaminated insulator
surfaces are investigated experimentally. The test results lead to the conclusion
that the variation in the flash over voltage is caused mainly by the characteristics
of conductive films formed on the insulator surface in the clean fog test.
