boy, you sure could have fooled me when I was standing out there helping hold
one!  The hose ran right over to a cabinet with the big letters "FIRE" on the
side of it.

Solar fart strikes again...


Probably not enough difference to matter.  The fire system at a typical plant
takes its feed from "service water".  That is, strained (to remove the big
chunks) river water.


Good plan.  I'd have been right behind you!

I visited my brother in Canada a few years ago and he said the method that
they use in some areas in North America is to adapt a fire fighting
helicopter with a high pressure washer pump and then hose down the
insulators and lines with water to remove crud build up and ice during
blizzards and ice storms. Apparently as long as they stay above the height
of the power lines there is no risk of grounding the electricity via the
helicopter.
I am told it works very effectively with a relatively small amount of water.

Live line washing and conductance is related to water droplet size. It is
not a new procedure.

 It isn't a new procedure and they don't use a fire hose. Somebody was
dreaming that one.

I think Neon John started that, but I have to agree with him.  Watched them
do it in the San Francisco bay area where sea salt is a problem.  But I
can't remember if they killed power to the line first, or did it 'live'.
That was a *few* years back.
