High power transformers under load at CERN

[captinjingles]

Sunn O))) is that you.

Es cierto, el sonido de 50/100 Hertz es terrorifico, da una sensación de temor o pánico que el de 60 Hz no produce, no se cuál es el motivo exacto de esto. Vivo en un país (Argentina) donde la red es de 50 Hertz.

what a beauty sound!

[RoyHess666]

That sound is awesome, somehow I cannot stop listening to this :)

[YTBYTBTB]

awesome !

thanks for posting

What you hear is actually 100Hz.

When current reverses 50 times a second the iron core of the transformer undergoes

magnetetostriction twice during each cycle. In other words, 100 times per second induced fields cause

the core to stretch slightly; a meter-sized transformer might stretch or shrink by only a micron but this

would be enough to set up an audible 100-Hz hum.

@stenkind Interesting, Playing this through my ASA I confirmed harmonics at 100Hz and 200 Hz

[Odyseu55]

@stenkind So THAT'S how magnets work!

[redsquirrelftw]

Wow did not realized 50hz was still in use, and it almost sounds like a saw wave more then sine wave, guessing that's due to such high load. Don't think I've ever seen that many huge transformers in one spot other then a hydro owned sub station.

[xXxmidgexXx]

I prefer 50 hz to 60 hz IMO.

"In most parts of the world this is 50 Hz, although in the Americas it is typically 60 Hz." - Wikipedia

@ Redsquirrelftw: Many countries use 50 Hz.

The strange sound in this video could probably be cooling equipment, used to lower the temparature of the oil that cools the transformer.

[mediarocker543]

It does sound like a saw wave. I gotta agree, but its probably because its being converted and its prior to cleaning it up to a sine wave. I know that many tranformers distort the wavelength often times to a square or saw wave, and then they use capacitors to clean the wave up and make it a pure sine wave again. I dont know, its just a guess. :)

[mima14031985]

Probably the strange noise it's due only to the metallic components of the transformers, which vibrating at line frequency they adds higher harmonics to the 50 Hz fundimental frequency (like a guitar string vibrates at its fundimental frequency + some harmonics). In such big transformers the waveform it's always a sine and all is done to prevent waveform distortions or the transformers will overheat.

380 kv ?

[Mosfet510]

eerie sound! cool video

[maDa3k]

uhh.. scary sound.. thats seems to be a serious amount of power that is beeing transformed.. to LHC maybe?

[ARR016a]

POWAH!!!!!!!!!!!!!!!

[xXxmidgexXx]

POWER!!!

[ajs2120]

50HZ the best!

[mexicanerd]

jesus that's just scary to be around

[mediarocker543]

Yeah especially at night by yourself. :)

[XmegaPresident]

Sounds like 50Hz

[Triodus09]

Yep. CERN is at Geneva, Switzerland. 50Hz of course.

[mediarocker543]

yep, go to audacity and generate a 50hz sine tone. Exactly what you hear.

[poweredbyibm]

Que impresionante... imagino caminar por ahí descalso y que se pongan en corto, y las mangueras de cables comiensen a dar latigasos ensima parece que acabo de llover, esta el piso mojado...

Lindo pero terrorifico

[altheo]

nice sound !
