Where did you get a 15kV NST in the UK? I though they were limited to 10kV max by law here...
-
Can I try now?

@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.

have you seen the 22 Kv wire at singapore's HDB hub?
-
Does it have a Ground Fault Interupter built into it?
-
not 20khz. that be 60hz brah
-
damn way undrepowered
-
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?
