Utility Fence

[Kavika21]

We have a project and we installed a new motor operated fence (160ft) around the perimeter of the building. Local utility company indicated since the fence is under their 66KV line, they want the fence grounded. Does anyone have recommendation what the ground requirements for the fence? Thank you.

Is the fence parallel to or perpendicular to the power line?

Most of the utilities in this area have 'details' for grounding the fences around their yards, maybe you could use one of them.

Is the fence parallel to or perpendicular to the power line? We have a fence that is perpendicular, if the cables are cut they would hit the fence. We also have a fence that is perpendicular and located 100ft away, if the cables were to drop.

I did not see any Rule requirements for grounding the fence with this Utility company. If you have any idea what rule this will be under that would be a good starting area.

180.60.20) Metal property fences installed on the Customer?s property shall be grounded to
ground rods installed one foot inside the fence at corner posts, gate posts, and at posts on each
side of an overhead transmission or distribution line crossing. No connection with the substation
ground system is necessary where a minimum separation of 6 feet is maintained between the
substation fence and metallic property fence. A buried conductor connecting gateposts is
recommended. Fence isolation sections may be utilized to electrically isolate extended sections
of property fence from the substation.
