  • Can you feel the beat?

  • I worked construction one summer, and a guy on the crew (who was an idiot) backed into a utility pole and knocked the wire loose from the other end, which was connected to a building. It carried far less current than this line, but every time it hit the concrete, it would spark and it was hot enough to turn the spot it hit into glass in a little 2 inch circle. Luckily, my co-worker was okay.

  • That thing has a regular pulse to it, LOL!

  • coulda set your clock by that thing

  • si esto es una falla a tierra por que el interruptor o disyuntor esta realizando mas de 3 pruebas de cierre, por lo general son 3 y se bloquea por seguridad

  • no wonder this stuff can kill you

  • było zdjąć buty i czekać aż dotknie ziemi

  • Lol alternating currents.

  • @tall32 guy Japan has both. Northern half 50 Hz Southern Half + Okinawa 60 Hz. We lived there 3 times everything is made to work on either whether as-is or simple conversion. In the case of record players and tape decks change pulley because speed of motor is 1 turn every cycle 50 Hz 2500 turns per minute 60 Hz 3600 turns per minute.

  • At 50 Hz it is 3000 rpm not 2500 rpm!

    n= 120f/p

    n- number of rpm

    f- frequency

    p- number of magnetic poles

  • Thanks for the correction! In the case of a RCA color TV we had, it was made for 120 v 60 Hz. Guess what happens when you feed it 50 Hz at 100 volts: it smokes! Apparently 50 Hz causes it to draw too much current despite the lower voltage. The ratio of 50 Hz to 60 Hz is the same as the ratio of 100 volts to 120 volts: 0.8333:1I can see a motor drawing excessive current if operated at a lower voltage and frequency that it's designed for but a transformer? Must be other factors I don't know about.

  • @Nivicoman That's weird. I've never had any problem with 50hz vs 60hz in anything I've used, even induction motors seem to cope (I assume this is because there's a safety margin built in). Was it a really old TV? They used to use the line frequency for the vertical refresh, maybe that confoozled it.

  • @pchapman905 I remember the tv when I was 4-that would be 1969. First the flyback high voltage transformer blew a few years later in the Phillipines (110 volts 60 Hz). My dad had it fixed. Then a couple of years later in Japan on 100 volts 50 Hz a transformer blew, don't remember if it was another flyback or the power supply transformer. Might not have had anything to do with the 50 vs 60 Hz thing just one of those things. Hard to remember exact details 35 years later!

  • @Nivicoman Ha, I wasn't born for another two years :D That's so long ago I have no idea, there were still tube TVs then! I've moved between Canada and Europe several times and brought things like clothes dryers and power tools and TVs and I've always been able to make everything work

  • @Nivicoman (PART TWO)

    If you decrease the voltage the appliance will try to compensate by drawing higher current (thus creating an over-current). The transformers are generally robust and can withstand over-current for some time but electronic components are very sensitive to over-current and can withstand it for very short time. Thus they tend to burn out.

  • @m3850d A.K.A. a "brownout".

  • @m3850d

    For the sake of it we can take

    P = V^2 / R

    I know its AC in this case, but the point is the current depends on resistance, if the voltage drops and the resistance stays the same, the current cannot grow.

  • @TheEndlessSilence An exception is induction motors. If the voltage drops the inductive reactance of the winding decreases, causing an increasing current to compensate. But since this increased current causes heating of the winding many motors burn out because of too low a voltage instead of too high.

  • @nakayle Interesting, first responce i have gotten on youtube that i actually learnt something from. Thanks!

  • @nakayle Or the low voltage causes the motor to run slower under load thereby it generates less back EMF allowing more current to flow in the windings. A different way of explaining the same process.

  • @pchapman905 We used American 60 Hz space heaters with little fans, vacuum cleaners, mixmasters, Lionel trains fans radios drills with no problems on Japan 100 volts 50 Hz. I think even fluorescent light ballasts didn't mind the difference. It was air conditioners, refridgerators and other heavier loaded motorized equipment that was more picky.

  • @Nivicoman I doubt that transformer has to do anything with that smoke; but electronics does! The power necessary for most electric appliances is always the same and is calculated by the following formula: P=U*I*pf

    U-voltage

    I-current

    pf- cos of fase angle (suffice to say it never goes below 0.95)

    (PART ONE)

  • @Nivicoman This is easy- older TVs used power transformers. A transformer for 50-Hz must have more iron (laminations) than one built for 60-hz because 50-hz produces less inductance. A transformer built for 50-Hz will work on 60 but one built for 60 will overheat on 50.

  • @nakayle From that I take it that transformers and motors rated for both 50 and 60 Hz operation are actually built for 50 Hz. On small fans you can see the amp draw ratings for both like 50 Hz 0.26A/60 Hz 0.21A. I've seen a National (Japan) refrigerator spec plate showing 100 volts 50/60 Hz running for many years on USA 120 volts 60 Hz with no problems. Even the neon pilot light lasted for years on the higher voltage.

  • @m3850d I did the math wrong. Thanks for the info!

  • In the US it is 120v @ 60 cycles.

  • this happend during oone of my baseball game a pole just blew and did the same thing this did

  • That can't be too good for the old eyeballs

  • BOOM BOOM BOOM BOOOM BOOM :-D

  • hmm something tells me the reclosers aren't working very well LOL

  • Looks like the reclosers are working too well. Should have locked out after three tries.

  • wtf was that! lmao

  • The European electricity standard is 50 Hz while the American electricity standard is 60Hz. Depending from which company one country's government bought the first electric equipments to be set up, if it was an American company, then whole country will be 60Hz and if it was an European company, then whole country will be 50Hz standard. Brazil has adopted the 60Hz standard. The domestic usage goes from 127V to 220V, depending on the city you are. Voltages above these values are for industry use.

  • wow ur smart

  • Here in Italy it depends if you are a Berlusconi supporter, than you have 220V @ 50Hz if not, than you can by batteries or use the not picked up garbage as some sort of bio-energy. I'm still trying to run my PC on it... but the smell.... Terrifico!

  • Shure wasn't in Brazil, here the electric lines are full of protect fuses as in Germany, at least there is an half second burst, and the fuses imediately open in the substation.

    Unfortunately arcing and transformings explosions we only see in youtube, hehehe

  • i hear 50 Hz too. yay

  • The Netherlands is 50Hz

  • and throughout Europe is 50 Hz with voltages of 220-230 volts

    greetings

  • What a shit of protection!

  • Where's the DeLorean? LOL!

  • LOL is was like waiting for it to pop out :')

    and Doc with his shiny aluminium Glasses thing of him

  • gonna post that on every vid?

  • @dellsucksass DUDE EXACTLY WHAT I THOUGHT !!!! LOLL

  • sounds like techno music

  • ooww! That hurts! Geddit?

  • Nah.. that tower was either 69KV or 115KV. 230KV requires a lot more height.

  • The only places that have 60 Hz in the world besides the US and Canada is Saudi Arabia, Korea, and I think one of the South American countries. Everyone else is on 50.

  • 60Hz here on Brazil

  • OK there's the other S. American country I couldn't remember the name of! :)

  • in* brazil

  • Here in Chile is 50 Hz

    with voltages of 220-380 - 230-400 volts

    in this, in brazil the frequency is 60 Hz

    with voltages that are not fixed, with 127-220 - 220-380 volts approximately

    greetings

  • And Europe? It says from 50-60 on my charger...

  • Depends on countries, I think. In Hungary, it's 50.

  • I checked up. Its 50 as well.

  • That just means your charger can work with both 50Hz and 60Hz current.

  • at least here in Chile and frequency voltage is 230 volts, 50 Hz, and the whole southern cone is 50 Hz, (except in peru that follow the standard tesla and the frequency is 60 Hz and the voltage is 220 volts)

    greetings

  • Japan? and Liberia in West Africa

  • @tall32guy Most not all of the Latin American and Carribean countries are 60 Hz, Taiwan and Phillipines are 60 Hz also. Not sure about Guam. I'm not 100% sure but I think the reason the pumps that were brought in to deal with hurricane Katrina in N.O. burned out because some parts down there use 25 Hz and a 50 or 60 Hz motor will overcurrent on a much lower frequency. Much as an aircraft 400 Hz motor can't survive on 50/60. I even saw a warning on one saying it will burn out if used on 60 Hz.

  • Comment removed

  • yes, 50hz

  • Nah man was in australia (south west)

  • @wilddazz Australia is 50Hz i beleive, no idea how he worked out it was 50Hz just by listening though...

  • Ooooooo, what did you do!

  • wow looks like a ego shooter game!lol

  • Swiatla jak w Energy 3000 ^^

  • Energy 2000 :p

    ciekawe czy można jakoś samemu zrobić podobne efekty :D

  • Mozna: po prostu zazucasz nitke lub wluczke przez takie druty przywiazujesz do nich kija :D i odsowasz sie na bezpiecznom odleglosc 25-35m po czym naciagasz wluczke i kij dotyka drutu i ziemi, jeszcze leprzy efekt jak tu gwarantowany :D

  • Im scared!

  • cool man! keep it up!

  • Nice.

  • cooooooooll

    nice job

    what a bomb

    ahahahahahha

  • Almost as cool as that 500KV disconnector failure vid with the 60ft arc :)

  • Well this probably isn't any more than a 230kv, if that. So not nearly as loud and violent. But still pretty impressive!

  • BOOM BOOM BOOM all bow before the lightnng god, lol.

  • hahaha

  • hahahaha

  • AHCHZOOM AHCHZOOM! It's making a rhythm!

  • the equivilant of electrial love with earth

  • the power line wants it's bottle NOW!

  • sweet

  • what the hell O_o wow

  • crazy!!

  • Wow! Impressive video!! Hope nobody got too close!!
