@MrGoogfan Wrong and right... The 60 Hz sound is from the loading of the arc hearing the current intensity pulse with the incoming 60 Hz feed, these units are too cheap to have proper filter capacitance (1,000uf tops.) You can hear the 20kHz if you listen carefully, unless you are one of the people who cannot hear that high of a frequency. Adding a 10,000 uf or so filter cap in the internal DC inverter would get rid of that sound and improve wattage output. Real transformers are louder.
These high voltage arcs in air produce interesting chemical reactions by breaking the tripple bonds of N2 gas and bonding it with oxygen to create nitrogen monoxide and nitrogen dioxide as well as ozone by ionising the oxygen in air. Be careful about running these arcs in a poorly ventilated environment for long periods of time as these gases are toxic when inhaled.
...also, if you're interested, I do have a couple of vidoes that show how to build a typical spark-gap type Tesla Coil. But I don't know how a solid state transformer would handle it. They tend to be more sensitive to high frequency kickback.
Nice arcs! I prefer a straight AC transformer myself. I have four 15kv 30ma neon transformers. I have a few videos that show the arcs from those, including a small Jacob's Ladder WAY overpowered with all four of them hooked together in parallel at once. :)
its an NST arcing it like that wont burn it out, an arc is just a short circuit so is a neon lamp, neon sign transformers are ment to handle such stress
I always wondered how these NSTs with ferrite xfmrs deal with resonance. If I connect the right length of wire to the output of my ferrite-core flyback (driven by half bridge), it forms a capacitance on the output and when its right, it will resonate with the transformer HV winding, destroying it by overvoltage.
this is a good one to start with , ideal really ,,, 20ma 20khz , thats very good compared to a standard one which would only be 50hz, thats a serious increase in power without going mad on the danger
there not that hard to build,for your first one u can just use homemade capacitors(from 2 litre bottles) some thin enameled copper wire for the secondry
(1500 turns around a lenght of pvc pipe)
5mm copper tubing for the primary a simple static spark gap
Where did you get a 15kV NST in the UK? I though they were limited to 10kV max by law here...

Does it have a Ground Fault Interupter built into it?

not 20khz. that be 60hz brah

15KV=the Picture tube HV (big red wire) of a 13" b/W set. (The set can only put out 1 ma, and cannot tolerate shorts)

240h8r,
I didn't know that! I have built a Tesla coil and it produces hundreds of long electric arcs.

Wow, that is pretty cool. Did you have to do any wiring or did you just plug it in to achieve the visible spark?

Must be a ferrite core one, much like a flyback. Hence the high freq. Good one.
