It is shown that uniform field pre-breakdown measurements of ionization and attachment coefficients in SF6 require pd values below a few hundred mmHg cm, and that pd must be less than a few thousand mmHg cm to obtain proper uniform field breakdown voltages. Each shade is a fantastic, self-striping mix of bright colours, tempered by the flecks of white found throughout. These measurements were conducted in a dewar which could be pressurized from 1 to 2 bar absolute which greatly reduces the spontaneous formation of bubbles that can occur in open LN2 bath experiments and thus potentially reduce the breakdown strength.

Pre-breakdown discharge currents in SF6 rod-plane gaps are measured under positive switching impulses and at different gas pressures. WebThe electrical breakdown is a process in which a gas changes from electrically isolating to being electrically conducting [1]. When a negative voltage is applied to a rod electrode, heating on the anode caused by field emission from the cathode plays a leading part as with the sphere-tosphere gap.
