Abstract
Electrostatic-field optimization of the profile of the gas-dielectric interface was studied as a means of improving the dielectric performance of epoxy spacers. An optimum disc-shaped spacer was defined with a dielectric cone angle of 750, assuming a dielectric constant of the epoxy resin of 5 or higher. The dielectric performance of the optimum disc-shaped spacer is found to be limited, however, to about 85% of that of the conductor system without spacer.Keywords
