Could it be that a circuit breaker opened and auto reclosed that

Seems a tad quick for an auto recloser.

I rather think that the current flow wasn't that much, well on the scale
of the power that the OHL can supply.

I'm not thinking of a trip of the breaker due to overload but due to earth
leakage. The auto recloser on the 11kV that feeds us trips on earth
leakage. One of the insulators starting tracking over on the top of the
pole outside, we wouldn't have known if we hadn't been oustide and heard
it crackling, enough to make the auto-recloser cycle through it's three
trips in x minutes = lock out. I think we would have been aware of the
noise from inside the house if it was overload that close causeing the
trip...

Theres been a lot of debate over on UK Railway as to whether or not a
video such as depicted there should be used as a public info film to
warn of what can happen if you should touch those harmless looking
wires..

It's certainly an idea but not for "general release" maybe part of a
targeted campagne within schools in areas where playing on the electrified
railyway is a problem. I think the teachers would have to be told about
and consulted before hand and some form open discussion held afterwards to
talk about it.

Anyways lets hope he's at peace now .. poor sod;(..

If the footage could be used, he may not have died in vain.
