While driving one day during a bad thunderstorm, I witnessed a branch from a tree land across all three phases of a 7200V pole. Beautiful blues, yellows, oranges and purples in the arc flash... (neat!)...

Anyway, I immediately pull over into the first driveway I see and call th PoCo. I give them GPS co-ordinates and figure that's about all I can do, so I tell the home owners that the PoCo has been notified.

Well, the thing continues to burn, a green branch in a downpour, mind you... but I got places to go, so I leave knowing the PoCo will be on their way and there's nothing I can do.

Turns out (after I left) the one phase OCPD never opened up, and the tree branch continued to be energized and burning until it burnt the conductor in two at which point it goes dancing all around until making contact with the TV Cable.

4160V (to ground) on RG-6 is not a good thing.
