Could the breakdown voltage of air significantly go down in very foggy weather (especially very salty fog from seawater)? Kind of a hypothetical question, but if anyone has something on this, I'd appreciate it.

  • $\begingroup$ I'm not sure what to make of this considering that air is mostly nitrogen: "for gases (e.g. nitrogen, sulfur hexafluoride) it normally decreases with increased humidity." - "for air, dielectric strength increases slightly as humidity increases" $\endgroup$
