Title:
The influence of surface roughness and dielectric coating on AC and DC Breakdown Voltage in SF6 
Chapter contribution:
I-02 
Abstract:
The surface roughness of SF6 insulated systems has a significant influence on the breakdown voltage especially at high gas pressures. Small surface irregularities can reduce the breakdown voltage. A thin dielectric coating could be a possible remedy. To evaluate the influence of rough surfaces with and without dielectric coating the distribution function of the breakdown voltage is of interest. Low probability quantiles and the influence of the first breakdown are relevant for...    »
