Re: Passive Ballasting for DRSSTC - My thoughts before Ed Wingates Teslathon

I assume both of you (Ed and Dan) are measuring peak current with a 
CT on some sort of grounded target?  I can easily perform this test 
some time, though the accuracy of any number i arrive at will 
probably only be good to maybe 10% as i dont have an oscilloscope 
that displays the exact value of the peak (i just have to judge it by 
eye).  Or maybe i can borrow my friends DSO.

Dan, did you measure any difference in arc current with say a 2 foot 
arc and a 4 foot arc?  I would imagine the shorter arcs might have 
more current through them (Assuming you have the coil running full 
power in each case), but this is dependent on what the actual 
impedance of the ionized channel is.  I suppose i can test this 
myself if you havent already.  Actually... im wondering why i havent 
performed this test yet.

Thanks.
Measured peak arc current of my DRSSTC II system is 3.6A peak.  I'd be
curious to see what
Steve's coil did.

Dan,

I measured a peak arc current of 15 amps. I have no idea if Steve has
ever measured the arc current of his coil.

Measured arc length is 14 feet and building limited.
