I recylcle electrical transformers at my job and the older ones do contain PCB's. Some of the oil in older ones carry concentrations upwards of 5000 ppm which is quite toxic.
the oil will not call cancer and there is nothing added to it for fire prevention; older transformers have the potential to contain PCB, which is a hazard to the enviroment, so if you suspect the trans to have PCB it's a simple test you do on the spot, newer transformer oil is basically just "good ole" mineral oil
the oil is for cool ing if you see on a little bigger transformers there are tubes and the tubes help cool. the oil down so that it doesnt get so hot and the little ones dont need tubes to help cool but when they get a certan age or if the slowly leak and loose a little oil over tine they get too hot then catch fire read my other comment and find out why to stay away from the oil inside!!!
you dont want to touch that oil you will get cancer they add something to it for the heat and when it gets energized it becomes deadly so just a little tip my friend works as an elctrin so he knows becouse a few people that have touched that have ended up with cancer
I live in the UK, London and the good thing about here is the fire hazards are a lot lower.
There is a few transformers in every town that are sealed away in gates, the power lines are under ground were there is no oxygen so they can't catch fire, there is also a back up transformer but it is only turned on if there is no fire, this is done automated by a sprinkler computer. The other clever thing is, if the transformer gets too hot, it shuts down to AVOID a fire.
@dymproductions, it's true that in cities across Europe transformers are underground or in special buildings as well as the power lines. Meanwhile there are still some oil transformers on poles in the rarely populated country side...
one time i was sitting in the back room watching a thunderstorm then all the sudden i saw a big shower of sparks then is came back on i knew waht happened if only i had my camera with me by the way nice video!

I translated this to english with google translate so people can read it:
Americans have always all at the nozzle and the wooden (!) Poles. In Russia, power substation being built and wooden poles have long since not been used - only reinforced concrete. In short, when something is before a fall.
It was probably overloaded, prob. because when the neighborhood was first built, they put up a transformer with the rating to handle the original load. But overtime as people probably built onto houses and added garages, etc., the demand for electricity rose, causing the transformer to get overloaded, and eventually overheat and catch fire. The old one looked like a 50KVA unit, and they replaced it with another 50, but also added an extra 10, 15 or 25KVA transformer to handle the higher demand.
The way that power companies designed the lines back in the old days probably caused a lot of old transformers to explode. Notice how there are 3 bare wires below the transformer... those are the outputs. all you need is a tree or something to short out those bare wires, and you get a transformer explosion! Nowadays, the output wires are insulated, and wrapped together, rather than exposed like in this video
@rsp196607 You're such a retarded dumb-ass. That tranny was only 10-20 years old. They are designed to last upwards of 40-50. This one failed before its time. NOT THE UTILITY COMPANIES FALT!
what your Thinking of is Pcb's...that was used as a coolant in transformers up to the Mid 70's....then they switched to Mineral Oil...something that was not Toxic.
my friend and i were standing outside his house and heard this zzzzzzzzzzzz noise from a long way off, it turned the corner heading toward us zzzzzzzzzzzZZZZZZZZZIIIINNNGGG!!!! It was like a ball of lightning hit the transformer and BOOOOOM it blew up, scattering fire everywhere. we were about 30-40 yards away. this occured in a matter of seconds, we heard the sound coming from about a mile and a half away.
this was on a hot, clear day, I'll never forget it.
I wish i can get a new transformer. Mine most have PCB'S in it it looks soooooooooooooooooooooo oldddddddddddd. The pole holding it outside my house looks like it will crack in half. The pole vibrates if u touch it. And it buzzes loudly sometimes.
since mineral oil is not toxic your grass shouldnt have died like that,if the transformer was sorta old then this is most likely pcb's wich is very toxic.
It could be that the line that caught fire because it was heated with overcurrent for a long time, and then to melt the insulator material which seems to be that thing dropping. I am just guessing.
This could have started due to a high resistance [corroded] connection on a day when the current load was high. As the connection heats up the resistance goes up and the process snoballs.
Haha, it is so funny how little the general public knows about anything. As nate said, there are PCB's in a lot of old pots, thats why the grass is dead...not acid, it is actually oil in transformers. Nowa days it is like cooking oil. There shouldn't be any hazardous voltage output, it is a single phase transformer, if it had been a three phase bank...then maybe. Leave comments so people who know what is going on...thanks.
single phase input and two phase output. each phase runs 120 volts going to the house. but when first phase meets second, it becomes 240 volts. i have a smaller transformer that acts the same way that is used for electronics.
single phase, split phase, three wire, unicorn type transformer, to be precise.
Was it leaking because of corrosion or because the oil overheated, boiled and started to leak at the top (i dont think this was the case), and then what did ignite it? I have to guess it was a continuos arc from the HV tip to the transformer or something.
i think overload coused the oil to boile and the presure velve opend and air rushed in to set it on fire

That's odd. I don't see a cutout (high voltage fuse and switch) on the old transformer, but at least there's one on the replacement.

It was rainy and windy today, and about 20 feet away...the power pole's transformers exploded like this, and there was also 3 loud pops!
and the electricity for the small strip mall went out.
I was the closest, and probably the only eye witness! it was alarming

There's some acid stuff inside a transformer so if it's leaking, don't get close. That's why the grass is all dead where it was leaking.
