150kv X-Ray Transformer

[@psyychonaut1787]

hook it up to a big big voltage multiplier!

[@VIKEHV]

That thing is huge! Great find. I hope I can find something that big in the future.

[@terberosity691]

There is some arcs coming off the output line to the ground

[@dronexfun8469]

am I mistaken or did I see some arcing between the caster of the platform and the lead going to the screwdriver? awesome video, I am hooked. SUB!!

[@ScienceMarshall]

Yes you did! It's pretty crazy. It arcs to just about everything it can. That's why I'm standing a long way back. Thanks for the sub! I always appreciate that. By the way, if you are in to big arcs I'll tell you my current project. I'm building a big SSTC and hopefully it will eventually be a DRSSTC. I'm still working on the drive circuitry but should have it done within the next few weeks.

[@johnruscigno5738]

Did I hear that right? You're going to power a fusion reactor with it? 😲

[@KyleMakeStuff]

Thanks for sharing.🙂

[@npcDroneClass]

Alright I trust a guy working with 150kv.... question!!! I want to discharge a 40" CRT, it's very scary looking. City cut the power cord and I need to replace it, but I don't wanna grab at it until I discharge (or do you think I Need to at all?) Also planning to do RGB modding later on.... SO, can I use some kind of pole with a screw driver attached to the end of it and short out the anode via alligator clip to ground? What kind of pole should I use? Wood? PVC pipe from home depot? Fiberglass poles with reflectors (the ones at home depot) and just remove the reflectors? Any chance the volts from the tube traveling up any of these poles? Thanks!

[@ScienceMarshall]

Yes, It is always good practice to short out the vacuum tube of a CRT before attempting to work with the circuitry inside it even though the charge may have already dissipated. I would use a PVC pipe, that is what I always use for HV stuff and it has not failed me yet! Good luck!

[@ThePaulPyro]

HOLY......Man, I am so jealous of that transformer...haha, but seriously nice video man! Those arcs are insane! :D

[@ScienceMarshall]

Thank you! I am super lucky that I won it. I'm not sure what all I can do with this kind of voltage now that I have it, but I have a few things in mind.

[@ThePaulPyro]

+Gooferking Science Well I'm sure you will find some cool stuff to do :p

[@TheBlork74]

there is nothing to be jealous about. This one eats electricity and can kill you

[@p0k7lm]

do you know how what gauge wire is on the secondary , the turns ratio. tnx ✏📚⚡📙🔬

[@scienceinnovativebrain]

1.which type of transformer oil you used (any specific name?) and how much it breakdown voltage . 2. transformer look like paper type insulation but overall insulation depends on quality of TRF oil

[@ManhuntFTW]

Very impressive!

[@mileslo_hobbies]

Be careful with the bucket handle, it could arc in betweem, maybe.

[@kamisama9715]

Did it just arc through the screwdriver? omg

[@bcikablam3578]

when it said "turn down volume" I forgot how loud it was... rip headphone users

[@KyleMakeStuff]

Awesome video!

[@p0k7lm]

that is, size of gauge on secondary ?

[@bartomiejdera4211]

Is it single or double phase transformer?

[@tf3confirmedbuthv54]

Bartłomiej Dera single phase

[@sylkelster]

Did you get that from chisoxt?

[@scubacertified]

The best I have is two flybacks wired together to get 60kv XD. It is also my power source for my fusion reactor.

[@hosensaum]

please make corona with this i think it would be awesome

[@ScienceMarshall]

You're right, I'll have to show the corona in a video. It is awesome! I will have to turn down the voltage so nothing is running open circuit at very high voltage.

[@la7yka]

Where do you buy good transformer oil? Have you some spex on the type of oil?

[@ScienceMarshall]

I just used pure mineral oil. I bought it off of Amazon. It is used as a laxative so you can find it in big gallon containers for veterinary use on large animals such as horses, cows, etcetera.

[@cisarvialpando7412]

Please clarify one thing. As looking at the sparks and sound, it seems like it is coming from a voltage multiplier. Is there a voltage multiplier connected at the high voltage output of the X Ray Transformer ?

[@unknown-ql1fk]

To answer the question, no voltage multiplier. The "snapping" you associate with multipliers are just the result of individual sparks, like what's seen here as well. If he ran more poweror closed the gap tthe individual sparks would merge into an "arc" with a different sound for sure. I know this b/c I have a few x ray xformers similar to these

[@inductivelycoupledplasma6207]

The snappy sparks is due to the parasitic capacitance between the windings and between the core and windings

[@edscac5891]

How much did the bill arrive from the electricity company?😂

[@anly7181]

can you yet cut stone?

[@muhaiminchoudhury2866]

What's the price of that transformer? How do you collect it?

[@jstuyfzand5467]

Does this work as a NOx generator?

[@ScienceMarshall]

Yes, it does produce some NOx gasses.

[@jstuyfzand5467]

+Gooferking Science can you make a nitric acid generator from it? in my country its really hard to find nitric acid

[@cisarvialpando7412]

Where can I get a X Ray transformer ?

[@PHM_Tech]

On xray

[@ayubyare6203]

it is cool.

[@Camroc37]

Did you see that Chemist Justin deleted all of his videos???

[@ScienceMarshall]

What?! That's really weird...

[@Camroc37]

Gooferking Science I know, I thought I'd see if he had posted anything but it's all gone

[@ThePaulPyro]

+Camroc37 Shoot! You are right, oh man I liked his videos... :/

[@Camroc37]

Paul Pyro it's a bummer, wonder what happened...

[@ThePaulPyro]

Camroc37 Yah, I hope he comes back soon.

[@secretagent5658]

Uh dude that isn't 150 kV! You're way off dude!! That's 600 kV!!! 3 kV per mm, 10 mm per cm 20 cm gap. Math is. 3*10=30 kV. So then 30*20=600 kV!!! Yeah umm.. That isn't 150 kV. So a little more dangerous.

[@ScienceMarshall]

Those rules of thumb for calculating voltage with spark gap length don’t directly apply to much larger voltages like these. An X-ray transformer like this is only rated for up to 150 kv anyways. The windings would arc over for sure if a 600 kv run was attempted.

[@secretagent5658]

@@ScienceMarshall Transformers all have ratings. But they can always be pushed way beyond that. I've worked with many HV applications such as powerlines. And I can for sure tell you that in this case that rule of thumb is perfect to use.

[@secretagent5658]

@@ScienceMarshall And actually that rule of thumb does directly apply. Because insulation is linear. Due to those characteristics it is a great rule of thumb. Now if you are referring to arc striking length. Yes the arc distance doesn't relate at all. But in this case its directly related. In this specific case 600 kV is a great measurement. Usually spark gaps have rounded edges to measure that. But through my research and experiments. Having a sort of pointed end doesn't mean very much. So 600 kV is a great measurement. Due to the way HV behaves this is true. In this case the 600 kV is true. Without a doubt I can for sure tell you with my full confidence that there is 600 kV coming out of that transformer. Most likely due to some sort of inductor or core saturation. I've also studied extremely closely with magnetics and am actually working with the DOT to make a MagLev train. Now that includes thousands of volts and thousands of amps. If I didn't know for sure or knew what the voltage definitely is and that it isn't 600 kV I would also explain that. But its definitely 600 kV.

[@ScienceMarshall]

Secret Agent I have to politely disagree. A needle-like spark gap makes a huge difference. For spherical electrodes with a diameter much larger than the spark gap your linear approximation holds. But not for pointed electrodes. Take a look at the resource in this link: www.kronjaeger.com/hv/hv/msr/spk/

[@inductivelycoupledplasma6207]

@@ScienceMarshall I agree with you. The 3kV per mm only works with very specific electrode geometry and completely breaks down at higher voltages (especially with pointy electrodes). I have a huge 33kV PT and the arcs easily strike at 50mm with nominal voltage applied.
