Re: Official air breakdown voltage?



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

It is common sense that air pressure, humididty, current, and time of day all affect air breakdown voltage, but:

IS there any official way to determine exactly what air breakdown voltage is? ( such as KV/distance ) "

Use spheres as terminals at both ends of the spark and use tables of spark distance vs voltage as a function of the radii of the spheres.
These are usually for low frequencies or DC of course.
