Would a flyback transformer trip the breaker if used for ctb?

Hi,

This is not my method, but I am very curious as I dont know if it's possible.
Remember old CRT televisions? huge fan of these things. and I was thinking, on a common 50cm color TV from the 80s, the flyback transformer pulses at 50hz, DC, 27000 volts. On your chest, going through your heart, it would hurt like fucking hell, but would it work, or trip the breaker (assuming nothing pops in the TV)? any chance of survival?

Again, if you're considering this method, DO NOT try it. The pain from ONE pulse is unimaginable. This is not a megathread discussing this stupid method. Keep your CRT TVs working. I'm just asking this out of curiosity.

I've heard many stories of people getting shocks from CRTs but that's from the capacitors?
But if it was plugged in and you touched the transformer I would think it should trip the RCD as you are now the path to earth. Eventually the MCB should trip with low enough Zs but the RCD would go first.

I would imagine if there's a path to ground it could trip the breaker. As far as I understand it, if current flows between the mains and the ground this would trip it.

I'm glad you aren't considering doing this as it's very painful. Having worked in another life, in an electronics store with CRT TVs, simply getting a belt through the screen across you chest is rather unpleasant. It was a "prank" people used to play, one person has the screen against their chest putting it on the shelf, the other plugs it in and switches it on then BRRRRLLLLPP!

Might explain why my ECGs are dodgy come to think of it lol!

I've also gotten HT shocks from a car distributer at high revs and that was horrible, I suspect the fact that I was headfirst into the engine bay with my feet off the ground probably helped me stay breathing. I suppose back then at least I would have died doing something I loved to do lol!

There's also other things in the TV that would likely blow too and if bypassed could start a fire.

I love my old CRT monitors too though and I've conducted similar thought experiments. I concluded there were too many risks of failure and permanent disfiguring injuries.

Best just to enjoy the phosphor and electron beams the way they were intended I think.

Hi thank you for your answer!
Yeah obviously there are methods that are easier to access and dont destroy a beautiful TV Set.. hehe
I'm kinda surprised you're still alive after all the shocks you received ^^ I received plenty of shocks too, mostly 220V 50hz, and did stupid experiments like 'heyyyy lets put 9V AC on my tongue see what it feels like!' (it hurts lol and makes your tongue numb)
kinda like ElectroBoom lol

hugs!

Man! ElectroBoom is so funny! I always enjoy his videos on YouTube! First one was the electric guitar one! I laughed like a drain when I first saw it.

I am quite amazed that I'm still alive too. I've had the usual mundane 240v 50Hz from 13 amp stuff. I've had wires stick to me like I'm magnetic. I sometimes wonder if I'm an example of Quantum Immortality. The HT shock I got from the car made my entire torso tense up so much I thought I would burst and I felt jolts down my right knee and calf muscle, that bit was comparably more pleasant lol! I don't recommend it though.

I haven't put 9v AC on my tongue, but I have done the old trick of putting a 9v battery on my tongue to check if it's got any juice. Funny thing is, people freak out like I'm doing something dangerous, and I'm talking about people who claim to know a lot about electricity and electronics!

Incidentally, have you ever watched Adrian's Digital Basement on YouTube? He quite often has videos where he works on CRT Monitors and TVs. He recently worked on an all tube Panasonic TV from the 70s, was quite interesting!

Yes, I even remember black and white ones. Your enthusiasm for old technology is nice, but your knowledge is lacking. Flyback transformer does not pulse at 50Hz, nor it can be used as defibrillator.

You are right in the second part. You should not consider shocking yourself with this. If you have uncontrollable urge to self harm with electricity, get some low powered taser.

I don't think his knowledge is particularly lacking. At least not in terms of the parameters of the question. He may have gotten the pulse width wrong but they certainly do pulse. He is aware of the high voltages involved and they certainly could be lethal.

Knowing that electricity is dangerous is not much knowledge. It is basic stuff to tell if transformer is 50Hz or 15kHz just by looking at it from distance.

Oh really? Care to explain how?

Sheet metal for low frequencies, ferrite for high. BTW, ferrite is also the mysterious lump on cables.

Wow aren't you smart! A ferrite bead you say? Sounds like witch craft!

So what frequency is this one?

What;s with the tone?

 

[Flippy]

Tone? I guess that might be a good analogue for frequency. But while we are talking about tone, you might want to consider your own? Any news on that frequency yet?

It almost seems like you wanted this kid to hurt himself, and you are mad at me for discouraging him. I guess it's up to @watereyes to decide.

Did you read my response to him? That is exactly the opposite of what I advised him to do, along with examples of my own encounters with high voltage systems.

You are the one that recommended the following: "If you have uncontrollable urge to self harm with electricity, get some low powered taser."

I also think it's pretty condescending to say "Your enthusiasm for old technology is nice, but your knowledge is lacking." When in every way relevant to the question, his knowledge wasn't lacking at all.

You haven't shown any superior knowledge. You claimed you could spec a flyback transformer from a distance. Condescendingly told me that the "mysterious lump" on the cable was ferrite.

EDIT: I intended to point out here that the first linked image was in fact a basic transformer and not a fly-back. The second linked image was indeed a flyback but that "lump" I believe he's referring to is actually the silicon cup that attaches over the HT output of the transformer. It could I suppose contain a ferric bead to suppress noise escaping but I've not investigated this possibility myself. END OF EDIT.

Everyone who has responded, including yourself, has demonstrated some knowledge. But the condescending way you responded was unnecessary. I don't get the impression you are an electronics ninja, that's ok, neither am I and @watereyes didn't claim to be either.

 

[justsayin]

You are right. Have a nice day.

 

[Flippy]

You are right. Hava a nice day.

Would you at least like to know where the picture of the flyback transformer came from? You might find it interesting if you are into electronics. I mean it might not be super interesting but it's a genuine offer :-) I'm not exactly sure what I'm going to use it for so some ideas would be cool :-)

EDIT: I will leave a photo here. See what you think, it's pretty weird right? Maybe I will post it Off Topic so I don't hijack the thread if you are interested. :-)
