Re: [TCML] Sudden and unexplained destructive racing spark flashovers



Phillip -

Well, at that distance it's pretty unlikely that the ground rod had any influence on the failure.

In your flickr photo (http://www.flickr.com/photos/pslawinski/3666083302/),

how far away from the surface of the secondary coil is the ground rod?

The lower half of the secondary (that's facing the ground rod) seems to be
"spiderwebbed" with faint blue surface arcs.

I caught a pretty spectacular shot of the secondary failure.

Also I should point out that my DRSSTC has a 12" long secondary, and
12"x3" toroid.
