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. |

Hi, yes I saw it once, our team worked on the road where the transmission line was de-energized, but well done they did what was required of them! ! |

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. |
