Electric Arc 30cm 180KV

[VicTheMouth]

Very informative video.

[denelson83]

Those are 230 kV lines at the end.

Is anymore of this video available

[thomasking55]

Yes, a full programme.

please upload more! ;)

Cool.

I wonder if that glaze is toxic...

[thomasking55]

I'd bet it is. The entire series of (early 1970s) engineering programs featured really dangerous situations, like open baths of zinc, sulphuric acid and plastics vapours!

[Dishfarm]

And those people stick their hands right in it. Haha that's terrible.

[Dishfarm]

That's why I usually play it safe with the various chemicals I use, I don't want to be told that something once considered safe has caused me to get cancer.

[thomasking55]

Indeed. Here in the UK Health and safety got an uplift in 1973, and a lot in the nineties, and now it is really high due to the claims for petty accidents and compensation culture. If you need danger to have fun, it isn't here!

No more playing with mercury.

[ccoraxfan]

Liquid glaze is just solid material in suspension, likely fine powdered glass and some coloring in water. Not dangerous unless you were to drink it.

[jovicakluk]

ye it probably is

[everyonehasaidsok]

It's not the volts that make the arc it's the AMPS.

[thomasking55]

I beg to differ. A high current (like from a capasitor) will make a big heavy crack and a bang, but only any high voltage makes the JUMP. Once the arc of ionized gas is conducting can you pass anysuch current. This happens in a camera flash gun; there are two circuits.

The more I think about this the less I'm sure

I've seen a neon sign transformer make a 2 inch arc, and it runs at 15kV and only about 60 mA.

To create current you need a big electric field, if you have acumulated charge you will just have a spark, if the EF is continous you will likely have permanent current. Amps is just a measure of charge flow, does not have anything to do with strength of any electrical field (VOLTAGE)

[BenHutchinson1]

If you want to start an arc at 1/2 inch it takes about 15kV, even if the starting current is only a few hundred microAmps (this will be a cool arc). If you want to start an arc by touching 2 wires together, then pulling them apart until the gap is 1/2 inch, you need only a few hundred volts, but at several amps (this will be a VERY HOT arc).

So the amps versus volts depends on exactly how you intend to make your arc, and how much power you intend to deliver (power = amps * volts).

i want this transformer

[bjtaudio]

@jmartis2 - Yea I want it too, however they are very expensive, I was quoted $15,000+ AU to have one made, and the factory was generally not interested in such a small one-off order.
