RE: gap breakdown voltages

Richard -

You are correct there are many spark tables in electrical handbooks but they
are not particularly consistent. Spark length is dependent on many
variables. The electrical handbook tables are for specific conditions and
not for Tesla coils. That is why I made the graphs shown in the Tesla Coil
Design Manual. These graphs were made from real world Tesla coil data that I
had collected from coiler's information. All coilers do not agree on some of
this information.
However, no one else has published similar graphs so the TCD Manual graphs
will have to do for the present.

Hi Chris
		You'll find a spark table on page 12-2 of the
Tesla Design Manual, by J H Couture. I have several other
such tables, but none of them a particularly consistent.

Hello all!

I was wondering if there exists a chart giving approximate breakdown
voltages
through air. I understand that there are many variables, such as humidity,
electrode radius, etc, but  ballpark figure is all I am looking for.
This info is of interest to me in setting my safety gaps, and knowing about
where they would fire.

Thanks for any assistance!

Chris
