400/220 KV transformer-watter protection activated

[tall32guy]

That is one BIG substation! Wow! LOL

[astifan1]

@tall32guy yes,its one of bigest in my country ,400 KV substation plus 220 and 110kv levels.every voltage level has two bus systems.if one system goes malfunction there is other one to do the job.i dont work any more at tranforming stations,now i work at transformer factory.i m not sure about water,i suppose it is not deionized due to fact that systemis used almost never so no danger minerals jam something

[tall32guy]

Is the water deionized?

Where is this switchyard?

[astifan1]

@ApolloWasReal croatia-zagreb.i m just about to start to work at my new job and is is power transformers production

[ApolloWasReal]

@astifan1 Ah Croatia, the birthplace of Nikolai Tesla!

Zanimljiv način zaštite, čak ti i ne treba Buholtz :)))

[paul9511]

how you clean after? and in case of automatic set off,cause to a real fire,there are an automatic switch for shutdown the power or it's manual?

[paul9511]

the power is off before spraying the water right?

[astifan1]

@paul9511 yes

[gamesman12]

The water itself is designed to come out in such a fine mist that it suffocates the fire. It doesnt cause the same problems as you would get when you add water to a chip pan fire.

[gamesman12]

Alot of the fire deluge equipment in the UK is designed to operate without the risk of tripping out the transformer.

The fire fighting equipment itself is a series of water pipes which are filled with compressed air. This compressed air pushes against a valve which prevents water flowing. If the air pressure goes. ie a bulb melts due to heat of fire. Then the water shoots down the pipes and puts out the fire

[OnnomonnomonnO]

was that transformer running while the water was applied? thanx

[dividebyN]

My 2 replies to astifan are in the wrong order due to the strange changes u-t made to comments recently.......Thx u-t......!!!

[cheetawolf]

ummm...a WATER system for ELECTRIC fires?

one word-lol. ._.

[astifan1]

@cheetawolf after malfunction on trafo the power breaker cuts it from the net (if it works properly),and the fire that burns after trafo is disconected is a result of a burning oil (its loaded with oil,coz oil is needed to transfer heat from core to radiators),so water is here to turn of that kind of fire,not electrical discharges.

[FreonRose]

@astifan1 um isnt water a bad thing to use on burning oil?. last time i checked water makes oil fires spread even faster because the oil floats on top of the water. unless of course that water has some kind of foam.

[astifan1]

@FreonRose well i m not 100% sure,but what i now in this case its water,but sprayed as a mist. and a most of oil still should be in a transformer while its burning at some place.know that electrical failors cant be treated wth water coz they make electrolisis and divide water on hydrogen and oxygen which makes things even worst....maybe there is some temperature level below oil doesent burn,so if water cools it enought fire stops...

[FreonRose]

@astifan1 Might be lol. I dunno i was just wondering about using water on an oil fire. in most cases its a really bad thing.

[quantumbits]

@astifan1 YES if water was dumped on the oil fire it would be worse since you cannot coat oil with water like you can with a structure fire. But in this case a fine mist is used to suffocate the fire by displacing oxygen.

[pokesomi]

@astifan1 I think this was done with water for testing. they will empty the lines and change to a class c chemical agent.

[astifan1]

@pokesomi no,this is water system.if there is chemical agent there should be storage with high pressure tanks of antifire foam and this faccility doesent have that,i worked there for 6 months so i know.aldought at another faccility there is that kinda system,and tanks look like big fire extinguishers,all conected at same output pipe.trigering mecghanism was realy interesting,there is a big ballast wich at the time of activation star free fall and pulls all ventils open

[jeezzz37]

Water protection system should be activated only after all CBs of all windings of trafo are tripped

[jeezzz37]

Damn...

[allclear241]

Why wouldn't the electricity arc through the water to ground?

[narcoti]

@allclear241 Water is not conductive if it is pure (de ionized) But I still dont know why they would use water lol.. Especcially, it would be a electrical and a oil fire.

[IC2720]

Ok, let me see if this is right, the transformers are isolated from the ground, and electricity can't flow through a water stream because water doesn't flow in a continuous stream. If you really slow down a stream of water with a strobe, or slow motion camera, you see that what looks like a stream, is really a bunch of drops. So, experts, agree with this or not ?

[astifan1]

@allclear241 coz when water starts to run transformer is already disconected

[dividebyN]

@Bigsteve02, WHY persist in returning to view a video that YOU rate as 'Boring'? Where is the attraction in watching a video YOU would rate as 'boring'? Not to mention, if you think the vid IS boring, why post comments voicing your opinion on something you obviously have no interest in? Attention ???? I'll stick by my 'cool vid' comment thx! Cooool vid! ...lol...btw steve, try searching for, quote, 'sparks, flashes and fire' if thats what you would prefer to watch! Seasons greetings !!!

[BigSteve02]

comment to the YouTube viewers who gave my & Jtho53's comments the thumbs down, kiss our firm peach like bottoms. we are right this videoclip was and still is boring.

[ap327145]

uhhh no duh its boring if your a retard looking for music vids or my guess something from a gay ass transformer movie or some shit and ended up finding actual transformers, thats what they do not a whole lot, that being said very interesting vid, i wasnt aware substations had water protection systems

[sixstringsmark]

Interesting system. Thanks for posting.

[BigSteve02]

well Astifan i did not expect it to be funny i just wanted to see sparks, flashes and fire & maybe a bloody loud bang, something more exciting than a transformer being sprayed.  sorry DividebyN this videoclip is definately not cool it is really boring.

[dividebyN]

Cool vid, thats quite a large distribution set-up there !! Until I seen the source of the mist/spray, it looked as if the core was boiling off the mineral oil !!!..lol...(looked vaguely like the florida tranny that self destructed in style, eating its own core until the reservoir/skin burst causing the mineral oil to escape....(resulting in the fire))...

[astifan1]

@dividebyN i think that florida tranny exploded after its been heated wth burning oil,and later abruptly cooled wth water system.evrithing brakes if you heat it and then suddenly cool

[dividebyN]

With the greatest of respect, regarding the florida tranny, you are incorrect. There was obviously a fault on a secondary. That fault alone wouldn't take out the upstream protective device, (obviously, because it wouldn't have got as far as it got!). Internal arcing ruptured the reservoir skin, possibly with heat, (causing internal pressure),

[dividebyN]

or by just staight melting, causing loss, (and ignition), of its oil and the primary to short out, hence at that point it took out the H.V. fuse.(the next upstream protective device!) Wherever it's source was, a C.T. no doubt isolated ALL 3 phases due to the imbalance of a single phase going 'down'. Cheers.

[BigSteve02]

i agree with Jtho53, were the hell are the sparks, flashes and fire. it would make a more interesting clip instead of this really crap one.

[astifan1]

this is not supposed 2 be funny.i uploaded this vid so ppl who work this kind of a job can see this cause it doesent happen offten.

[jtho53]

Boring!
