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...
