I'm curious about the mechanics of power transformer expolsions. Keep in mind I don't have a real good understanding of transformers in general.
The other morning somthing (only guessing a transformer) made a loud bang, and then a very loud arcing sound, then we lost power. I was on my way to work, so I didn't have time to go look for the problem.
Assuming it was a transformer (thouse round can like shaped ones we have here in the US) What is likly to cause this on a cooler early morning (low demand) with no wind or storms? What exactly happens inside to cause the boom? What shorts against what? I would imagine they look black or burned after this happens? Do they spray oil all over? I have never managed to get a look at the aftermath of an explosion, and google didn'y yeild any photos.
Any current or former linemen hanging in the weeds here?
