Energized power lines on the ground pose a special hazard to the public (and electrical workers too)

This week's question is pretty simple. Have you ever seen an energized downed power line?

Yes
No

Stories are always welcome!

Of course it is energized until isolated tested and grounded. On that basis, yes. Not only did I see it, I moved it bare handed. The line served my house, and was down on my driveway on the load side of the break, and I knew I was was not generating. Nearly a week before the line crew got out there.

A lot of good Samaritans out with chain saws that week. "Is that line deenergized?". "No, let the power company deal with it.

At one of our Coal Mines we had 30 MVA Substation with a solidly grounded multi grounded 12 kV Wye system with feeder overcurrent ground relays.
At a remote location about five miles from the Substation, where the neutral was not carried, we had a downed phase conductor.
The rocks soil and copper fused into a mass before the relay operated.
