SF6 dielectric strength
SF6 dielectric strength
(OP)
I am searching for information in relation to the dielectric strength of SF6 in kV/mm. Please suggest publications that have the answer or tell me the answer. Thank you.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

for:
1.1.2. Dielectric Strength. Its dielectric strength is 2 to 3 times that of standard air and has high thermal stability. The dielectric increases with increasing pressure and at 3 atmospheres, the dielectric strength is roughly equivalent to insulating oil. These properties make it useful in gas-insulated buses and compartments which contain electrical switchgear components.

An old standard reference is Yew, Matheson Gas Data Book, McGraw-Hill, 2001.

for the SF6 dependence kV versus pressure at 12mm gap. Then, divide kV by 12mm to obtain the SF6 dielectric strength in kV/mm.
The original posting does not address a pressure at which the kV/mm for SF6 is sought.
