Study of Water Droplets Behavior on Electrical Machine Insulation Under the Influence of Uniform Electric Fields: the Influence of Some Parameters on Mica Sheets
Mica sheets are a vital component of electrical machine insulation. Although great attention has been paid to partial discharges and their deteriorating effect on such insulation, relatively little attention has been given to surface discharges. This paper investigates the effect of water droplets, their volume, their conductivity, their positioning as well as their number on the flashover voltage of mica sheets. It is indicated that all the above mentioned parameters influence the flashover voltage
