["POWELL, DOUG" <DOUG.POWELL@xxxxxxx>]

Gus,

This is a complicated subject and people go to school for this sort of
stuff.  The simple answers are found in a number of equations that primarily
take into account electrode spacing and electrode geometry.  Considerations
are also dielectric medium, air pressure, humidity, and to a lesser extent
electrode materials.

There is no single equation you can use.  However, there are a number of
resources I can recommend, the challenge is finding these in print.

"High Voltage Power Supply Design" by John A Collins, Hughes Aircraft Co.
circa 1980s

"Design Considerations and Data for Gas-Insulated High Voltage Structures"
D. B. Hopkins, Lawrence Berkeley Laboratory circa 1970s

"High Voltage Technology", edited by L. L. Alston Harwell, Post-Graduate
Series, Oxford University Press 1968

Subject: [SI-LIST] breakdown voltage (arching) equation


Hello all ,

Does anyone know of an equation that relates breakdown voltage (arching) vs
distance in a given dielectric medium, metal types ,etc?
I looked in Henry Ott's  book but did not find an equation.

Thanks in advance,

Gus
