Abstract:
The charge height of values associated with PD measured during
electrical tree inception and growth are processed according to the Weibull
distribution. Test arrangements, based on the needle-plane electrode
system, consider specimens having either a cavity at the tip or an intimate
contact with insulation. It is shown that the Weibull-function parameters
have close relation to discharges occurring in cavity and tree channels,
and that an indication of inception of electrical trees can be obtained.
