Title:
Influence of surface state and thin dielectric coating on the insulation properties of a coaxial electrode arrangement in SF6 
Chapter contribution:
T9-342.p 
Abstract:
The improvement of the dielectric strength of SF6 insulated systems by using a thin dielectric coating to change the surface state of electrodes was studied. The paper deals with the breakdown probability of a coaxial aluminium electrode arrangement with different surface roughness in pressurized SF6. Thin epoxy resins with different thickness were used as coating material on the inner conductor. The outer conductor of the electrode arrangement was polished and uncoated. The surface roughness...    »
