Re: Really big VTTCs
Original poster: "resonance" <resonance@xxxxxxxxxxxx>
I'm all ears.
Can you suggest a nice surplus tube that would handle 10 kVA at
around 7.2 kV? I'm thinking of a small 7.2 kV, 10 kVA pole xmfr for
power. Perhaps two big 10 kVA tubes running at 20 kVA into a 24 inch
dia. coilform approx 72 inches long. 34 x 8.5 inch toroid. Perhaps
with John's stattaco controller on the tubes.
By comparison, VTTCs seem to have topped out at a 4" x 20"
secondary, driven by one to four 833A tubes. The consensus seems to
be that you can get just about as good performance from one 833A as
with 4 of them, if you design the coil right. Perhaps 36"
discharges seem to be the limit for VTTCs on a good day.
Is there some physical or electronic limitation to the design and
construction of a really big VTTC? With the availability of big
surplus power tubes (10 kW or more) on eBay, and the possibility of
multiple parallel free MOTs for input power, is there a physical
reason why no one has built a 12 x 60 or 18 x 90 VTTC?
Ten foot sword like discharges would be neat to watch!
