Pre-breakdown discharge currents in SF6 rod-plane gaps are measured under positive switching impulses and at different gas pressures. The breakdown conditions of short air-insulated gaps under alternating non-uniform electric fields are investigated for providing an accurate prediction of the breakdown voltages of commonly used electrode systems.

The effect of the coating depends on the electrode shape, voltage polarity, pre-charging and the duration and form of the applied voltage [7]. 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.
