Abstract: SUMMARY The breakdown voltage (BDV) of compressed sulfur hexafluoride (SF6) 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 SF6 at 30 kHz have been developed from knowledge of breakdown characteristics of air and from regression models.
