The breakdown voltage (BDV) of compressed sulfur hexafluoride (SF 6) in the pressure range of 1-5 atm at 30 kHz, the frequency used by Navy for communications with vessels, is presented. Experiments were conducted in both uniform field (plane-plane gap) and non-uniform field (rod-plane gap). The impact of pressure on the BDV is quantitatively analyzed. The pressure correction factors for calculating the BDV of SF 6 at 30 kHz have been developed from knowledge of breakdown characteristics of air and from regression models.
