647A transformer

[vitorix24]

1,5v 647A = DEAD

[SchoonebeekPower]

@vitorix24 No, it isn't. 1.5volts won't kill you. Ever touched a penlite battery one both sides with one hand? That could kill you, cause it delivers more than 5 mA. R=U/I (Ohms law)

[vitorix24]

@SchoonebeekPower if you say..

[RavenRof]

jesus christ that sound when the transformer is shortted is creepy.

[TheEsseboy]

A Car battery can pu out 15 times its current for a short period of time (1500A for a 100Ah battery) It wont kill the battery ;)

[Diddleshot]

You should see the sort of stuff 'PhotonicInduction' does.

[thelightguy1]

Ahh the sweet sound of a short circuit :).

[slava199416]

да ты чо йобнулся с такими проводами 647А они бы згорел также как иголка!!!!!!!

[Tvimadur]

never 647 A, the wires would get blasted instantly...

[TeslaWasHere]

@Tvimadur Wrong.

[thdmtr]

hi can u give me the schematics for that mod? have you just changed the secondary winding from many turns to 2 or 3 turns of a thick insulated wire? thanks, i loved your experiment. peace.

[joblessalex]

Waaaa waaaa (connects posts together) WAAAGHHHHHGGHGGHH!!!!!!!!!!!

[bernard240vdc]

well if one only passes the current of a car battery through small items like that pin here it will not hurt the car battery because that pin is melted away before that battery has a sweat sure touching the two big cables together directly would be hard on the battery but thats not as exiting as whatching these little objects just about faporize away

[TheError404]

What's the primary impendance????? I want to make a toroid transformer :D

[08Kutt]

whats the voltage??? AWESOME!

[bernard240vdc]

ha ha no need for a beefy transformer to do this any decent size car battery will melt objects way bigger than that little pin i know because i have done it i guess you could say that is abusing the battery a big enough car battery can easely melt a 2 or 3 inch nail or screwdriver etc in short circuit a battery can maybe put out close to 1000 amps

[omegalab]

@bernard240vdc

Yes, and destroys the battery for sure.

[sovietduck]

you can do the same with a car battery.

[TheMonsterEagle]

it's extremly dangerous

[darkeyce02]

i dont see a transformer

[quantumbits]

More like 64.7 Amps I wold think.

[omegalab]

x10

[hydrogenix]

@omegalab Man... I solder with 320 amp in the workshop and i melt 1cm bolts with the transformer when i get bored...

[thdmtr]

@quantumbits are you fucking blind or what? watch again.

[quantumbits]

@thdmtr @thdmtr Oh yes I can see clearly!

It takes a MCM 500 (500 Circ mills ) Cable or a copper buss bar at least 1 inch wide and 1/4 thick to carry 600 amperes.

[TeslaWasHere]

@quantumbits That's a PROPER rating. Meaning for service duty, that would be the proper size of bar for it to reach and sustain a certain temperature above ambient.

[lukeyj15]

@quantumbits agreed, or even 6.47

[Pyromadness]

hi how do i calculate the output in amps? i swear power = current x voltage. i see some videos of people putting in 230v to a rewound mot an supposedly gettin 2300 amps WTF? isnt the amps limited to the power of the mot? like a 1000w mot with 2 volts = 500amps?

[omegalab]

This is not that easy. AC has 3 power types : complex, reactive, and real. Real power of an AC part is : U*I*cos phi.

The output current is not only the ratio of voltage and current. The transformer has an inner resistance, and the load (even short circuit). You cant reach several kiloamps with 1-2V. If you have a low resistance wire, and you put it as load, the current will heat it up in milliseconds, and the resistance of the whole stuff get higher and higher, and the current will drop.

[omegalab]

For more information, see norton and thevenin theorems, and AC powers.

[rapidchoper]

@Pyromadness Amps = Voltage (Volts) divided by the Restistance (Ohms)

[Digadogup]

@Pyromadness D: same shit for me wtf!1

[psytranceua]

сила!

[SmashCOBamberg]

damn could anyone tell me how to get the secondary out of a mot?

[omegalab]

You need an iron saw, and cut the secondary in one site. Then you have two stumps. And now you able to knock out the secondary with a hammer and a piece of wood, or something with a reactangle shape. You are ready.

[SmashCOBamberg]

thanx

[redtails]

Is the transformer from a welding device?

[omegalab]

No, MOT means : microwave oven transformer.

[j822bosh]

These tranformers are free if you know where to look. Be more worried about the fuse box. An emergency switch between the plug and the primary would hurt.

[valcerfabri]

647amp ??? Never!

[omegalab]

Every time, I want.

[redtails]

probably super low voltage

[omegalab]

Without load: 3VAC

Short circuit: 0,1-3VAC

(approx.)

[greatwhitenorth112]

LOL AT THE END

[BenHutchinson1]

How did you avoid setting the carpet on fire? It looks like the floor has carpet at least.

[omegalab]

This is concrete.

[BenHutchinson1]

That's good.

[BenHutchinson1]

Last scene you short out the transformer. Did it ever work after that?

[omegalab]

Of course.

[fabioffsvideo]

q bosta de instrumento de medição .........usa fluke caraio

[Simpsonsfan1993]

What cable size do you need to support that kind of intensity ?

[Thentalus]

general you need for permanently about 400mm² cable

[dokvictor]

bad

[51lvl]

HAHA shortcut in the end, sure wasn't all that good for the generator

[itsCATURAY]

oh god you killed the paper clip!!! how dare you?

[fuwafuwa9]

ぎょえええええええ！？

[vulkanizer56476]

I simply love the 50Hz buzz on end :)

[xXxmidgexXx]

Yeh. I think it shorted out cos ir become so loud all of a sudden.

[hunter95959]

damn!

[lilletizz]

IT'S ALIVE!

[codemsan]

2-4

[RODALCO2007]

Cool clip. The TX didn't like the 647 Ampères, it wouldn't last long under those conditions.

What VA rating is the TX ?

[Tab54o]

Yeah Im just wondering. Are you doing that on the carpet? haha.

[SlavaVB]

some guy posted a video of lighting matches with a laser pointer on carpet too

[triggerhappy77707]

wow.i put about 400 amps short current.that was it.the bigger the wire i suppose the larger amount of that juicy magnetic field is picked up....

[adamsonlinedirector]

how did you get so much current? how many volts is it?

[omegalab]

3VAC @ 647 amps. I rewind the transformer. Secondary coil :4 windings.

[niwakun444]

that transformer didnt sound happy one little bit

[digidude86]

I dare you to touch the output of that transformer

[triggerhappy77707]

wouldn't hurt him

[CommanderAMB]

the voltage is to low, but the current melts nearly everything. (^_^)

[Crashdance22]

Dude, how could that much current going through your body not hurt you? It would probably fry you to death, not so much by electric shock but by the tremendous heat!

[NutsandGuts]

Because it wouldn't "go" through your body, ohm's law you idiot, go learn something about electricity before you post dumbass replies...

[rgsgww]

fun way to blow a transformer up lol

[louvadeus2]

shit that transformer sounded pissed off...LOL

[codemsan]

yeah it did!!!!

[FeFe87]

Uh, kicsit dúúúrva
