Wow!!, Thanks for the pic, mate!. Pretty impressive, any idea where this is or what size Xformer it is?. Haven't seen anything like that, since we(the fire brigade) turned up at the Winslow sub-station(110kV)when it went on fire and we wondered how the h**l we were going to turn the power off, let alone put it out!.

got this back from one of my distribution tech friends after I sent this thread to him.
"Got the lowdown on that transformer fire. Ends up this was Florida Light and Power station. What happened (incredibly) was there was a phase to phase fault on the station bus and the protection wouldn't work because the fuse clip on the English Electric fuse was broken (a very common problem).
The fluid you see before the major fire is actually the insulating oil in the transformer because the arc actually burnt through the side of the transformer.
The next day FP&L technicians went out and checked all fuse clips, finding some 20% of all fuse clips broken. At present English Electric will not sell the fuse clips to any of their previous customers since they cannot guarantee they will be installed correctly (they cost $4/pair) but will instead will sell the whole fuse holder (for $30)."

mbhydro: Thanks for the additional information on this spectacular failure. It must have literally scared the $(^*$(*% out of the people who were fortunate (or unfortunate...?) to be eye witnesses . I'm curious about something...shortly after the insulating oil erupts from the transformer and ignites, there is a very bright flash and explosion, after which the "humming" stops. Can you identify (or speculate) what happened at this point in this event?
This is quite a piece of video...I've watched it more times than my wife has watched "Gone With the Wind" . Much more exciting...

is what happens when your sign crane or boom truck comes into contact with the primary lines on the pole line in front of your new building. I believe the diesel engine you hear idling in the background is the fire engine just standing back until the power gets shut off.
