Air?
    Free, self healing, good dielectric strength.
    Oil scares me from being flammable, tho many people
    use it.  I Have my doubts water can be kept
    sufficiently pure.

    best

I suspect liquid nitrogen would be best, and also impractical,but water is 
definitly out.
Thanks for tthe advice.
Tesla used boiled out oils which might be less flammable. Air is however of 
variable conductivty especially in the presence of ozone. Maybe if it were 
somehow possible to exclude air entirely, the oil could not catch fire.
