Jacobs ladder with a selfwound 10kV 1kW transformer

Another experiment with my transformer: A Jacob's ladder.
The transformer ist driven by a ZVS driver (supply voltage 39V).
At start of the arc, the supply current is relatively low, around 8-10 amps (300 to 400 watts).
When the arc rises up, the supply current of the ZVS also increases, up to more than 30 amps (above 1200 watts...)
The transformer wasn't even warm after making this video.
This transformer is much more powerful than a TV's diode split transformer. The estimated output current during arcing is 1 ampere. A DST only delivers 200 to 300mA, and overheats quickly.
Also, the arcs of a diode split transformer with ZVS driver are much thinner and are not crackling that much during rising the jacobs ladder...

sunday arvo bored???

@DrLaksative my understanding of air arcs -imperfect; to say the least- is that the very high potential voltage exceeds the dielectric breakdown of the colum of air between the 'trodes, ionizing the nitrogen or CO2 in the air, thus creating a conductive channel in the plasma which forms. the collision of charged particles frees photons which give the light (flame) that you see. it's like burning, only fancy.

that or my understanding is poor.

Is that arc actually burning gases from the air, or why its so flamy?

very cool, but something went "pop" in the end :D

cool love it.
