RE: [TCML] Quick and Cheap Toroid / Off Topic

["Phil Tuck" <phil@xxxxxxxxxxx>]

Brandon,
The minor diameter of a toroid will affect breakout: a bigger diameter =
more top volts needed to breakout #without# a breakpoint. If you think of it
as a comparison between a safety gap using pointed electrodes, and a one
using spherical balls, the latter one will always breakdown at a much higher
voltage, as its curved surface can retain its charge more. 
A side effect is that it will also slightly lower the secondary resonant
frequency through more capacitance, even more so if it is accompanied with a
bigger major diameter as well.
I'd say the size of a secondary is dictated by power. More power gives, or
should give (speaking generally) longer streamers, but you have to
physically make the coil bigger to accommodate those longer streamers.
Pushing 6kw into a coil whose toroid is only 4 foot above ground is
obviously a bad idea, and as everything is scaled proportionally you need a
bigger overall coil.
Lastly, as for doubling the NSTs and caps - see answer above:-)

So a larger toroid will offer a higher capacitance in the secondary circuit
and raise the standoff voltage for breakout without a breakout point. Do I
understand that much right?

What dictates the size of the secondary coil alone? Nst voltage? Amperage?

If I were to double up my nsts and cap bank, what repercussions would there
be down the line (larger primary coil?)?

Sorry, it's been a few years hahaha

Thanks,
Brandon
