4,000 volt power supply (microwave transformers)

This shows how I connected 2 microwave transformers in series for a 4,000 volt power supply I built earlier. I used a light bulb to limit current. When an arc is drawn from a transformer, it shorts out the transformer. This cancels out the inductive reactance on the primary winding because of mutual inductance, and you'll see the light bulb get a lot brighter. When the transformer is unloaded (no arc), the light bulb is actually dimmer than normal because the transformers' primary windings add impedance. But when you draw an arc, it shorts out the transformer and cancels out the inductive reactance on the primary circuit. This means less resistance, so the light bulb gets brighter. You can see why you need something to limit current! When you draw an arc from the transformer, it causes a current surge.

is the light bulb in series with the primary winding?

@MrSciencetificsasuke

Exactly. All it's doing is adding resistance to the circuit, so that when an arc is drawn from the transformer, it doesn't cause a short circuit and an overload. But I've also found that a light bulb isn't the best way to limit current. You can use anything that runs on 120 volts AC. You just need something to act as a load.

very educational and knowledgeble on your part

[DougieB1337]

Errrh, your transformers are connected in parallel?

@MrPeterBurban sorry but thats what the lable read

[MrPeterBurban]

@67tr876 I don't think that you saw that correctly. If your numbers ware correct that would have been a 6,000 watt transformer. Volts x Amps = Watts That's like two electric dryers running at the same time. That's really high. Maybe it was 2000 volts @ (decimal).3 amps that's 600 watts much more realistic.

Really great video. Good explanation. Thank you.

@leaualorin 10000 volts - 1cm, so 4000 volts - 4mm

[thewinermaker]

use pwm

[67tr876]

I hope you know how fast that can kill you. Most microwave transformers put out over 1 amp ! I saw one that was 2000 volt at 3 amps ! You would be dead in a sec if you hit that !

I think I will just play it safe with my 5V DC breadboard projects!

FOR NOW, The only high voltage I use is my 1,000,000V stun gun -=]

Can you explane to me how to wiring one MOT? I not understand 3 wires on secondary.If I use light bulb,can I make ARC for long thyme?Do I need capacitor?
