Cool. Well i am sure i wont be doing this any time soon.

Hehe thank you :D Yeah it's better to stay away from low frequency high voltage, this transformer makes 230VAC sound like a child's play.

I love this clean MOT-Setup. Well done!! Crazy how big your arcs get. I also love the blue color :) Pole Pigs are really nice, you´re right. I wish I had one too.

Awesome. . Those arcs resemble the arcs they get when the national grid switch over. Love it. Keep up the good work.

When calculate the wire length of the winding I prefer to use the center layer's dimension.😂

Wow that's amazing 😅👍

try 6 in series-parallel 6.6kV configuration for much bigger arcs. (which can cause flashovers, so to prevent that, put them in oil or use safety gap)

I have bad experience with using more than 2 series MOTs. I've had flashovers even with safety-gap. For example when safety-gap arc quenches there can be short moments when the safety-gap is opened, leading to overvoltage on a MOT. I've destroyed too many MOTs trying to upgrade this power supply to 4S2P combination.

@@breezetix yeah that's a good idea. But the thing is it's too much work. Making a leak-proof casing. Not to mention that it already weighs over 60kg, in a tank filled with oil it would go over 150 maybe? The beauty of MOT for me is that it's fairly simple and robust high voltage power supply. If I wanted something reliable but maybe not as simple to do, I would just design a power supply that's intended for this purpose. Maybe a switch-mode inverter with large ferrite transformer.

The calculations are very interesting and well explained! But have you tried running the supply with less capacitors? I built a very similar stack to yours with 8 MOT's but only 10 MOC's (I would have used something like 12 to 14 if I had more). With all MOT's connected I only had primary peaks of 25A when arcing. I have 32A B-breaker so I am jealous about all the transformers and caps you have : D. Also use salt on the electrode to get longer orange coloured arcs. I had good experience with using graphite rods as electrodes to cheat a little on arc length as well.

Thank you so much! Keep in mind that the calculations are more of an estimate though, I assumed many variables. A good point, I haven't tried to use less capacitors. I noticed a rule of thumb for a guaranteed result to use 2 caps in parallel for each MOT. Maybe I will try it later to use less/more caps. This is definitely not the last time I've played around with this transformer :D

the arcs from that supply are a little smaller than I would expect from so many transformers... maybe the arc doesn't represent the real power it can output. I want to make one of these now, 6 more transformers and like 10 capacitors to go!

@@Astri.electronics hah, can relate. My two transformer setup it tripping a 15 amp breaker, even on a variac set at ~75% (as a ballast and to vary the power.) I'm planning to get a plug that I can modify to use only a single phase on a 60 amp breaker for my dad's car charging port.

record another video putting salt to post arcs to get bigger!!!

hehe I'm not really sure that salt makes the arcs bigger, I cannot really find any reasonable evidence for this but I'll maybe give it a try. Just recently I rebuilt this power supply so that I can use all 8 MOTs without tripping the breaker so a video will come out soon!
