OK!

Here's my 2¢. In Southern Calif. Edison country they have a truck
with a supply of
water, pump, and nozzle (much like a fire truck) to wash the
insulators. After watching
one in action, I asked the operator if it was to wash off the
conductive "road film?" His
answer was, of course, yes, and more important the salt film. This
was at the foggy
coastal community of Isla Vista next to UCSB. BTW one can hear a
continuous discharge on
foggy nights.

I suggest that the pwr. co. in Price UT invest in such a truck, or
better, since not a
frequent occurrence, rent the local fire dept.'s.


I gonna bet that the power company doesn't bother to remove
the voltage when they do this 'wash down'. The current that flows as
the wash occurs will quickly dry the insulators!

The local (Duke Energy) utility has automated breakers on main lines
that will attempt to 'burn' a short circuit by interrupting the power
and resetting it a few times before it shuts off for good.

Our local residential neighborhood has one-shot fuses in a few places
that squirrels or icy limbs can 'blow'.
