Substation Property Line Fence Fail IEEE80
Substation Property Line Fence Fail IEEE80
(OP)
I cannot pass IEEE80 touch potential criteria at a substation fence built on top of the property line adjacent to neighbors. I cannot move the fence inward three feet in order to get a horizontal ground conductor three feet out from it as this restricts our ability to get to the substation equipment. We thought of a vinyl fence but the fence vendor will not guarantee any dielectric properties of the plastic coating as his coating is only for weatherization/ aesthetics purposes. Any suggestions???

To JG2828- Your thoughts about using AMICO non-conductive fencing is fantastic! This brochure showing it already installed at a substation is a convincing element to use it. Some of my colleagues question the ability to break in as it is composite plastic... but then so can using a bolt cutter on a steel mesh.
Anyone with thoughts contrary to using the AMICO fence?

Well there's always the fact that anyone consciously breaking into a high Voltage substation to steal copper will get a grand dose of what is deserved. But it does pose a concern about infrastructure security. But as you've already stated, a chain link fence is not exactly a maximum security barrier. I think the product looks extremely viable and would be an improvement aesthetically over chain link. I don't think the neighbors would object at all.

Could that same felon/trespasser break through a chain link fence?
Yes.
Would that person "see" an obvious difference when he drove past this new plastic fence to say "Hey! I can now break through that new fence and get killed trying to steal electrified copper!" If the thief can't see a big difference between the new fence and the old fence, and he doesn't know there is a difference in strength/cutting resistance between the old and the new fences, why would he now try to to break through the new one if he has not been breaking through the old one?
OK, so buying the 3 foot strip has been ruled for some reason.
Also: Can you get a "utility easement" type of a rental agreement with the current landowner to bury a grounding wire under his property? After all, you would be the one paying, he can still use the property - even TX farmers don't plow all the way to the fence! - and the new wire is undergrouand and NOT a visual obstruction.

The racookpe1978 proposal of getting a "utility easement" type of a rental agreement could be a better solution than trying to insulate the fence [IMO].
RE: Substation Property Line Fence Fail IEEE80
This is not a recommendation without more work completed by experts and researchers, and the custom solution might still constitute a legal liability simply for not being normal.

Anyway this separate grounding will be influence during a fault, but It may help you to limit the touch voltage in this area.
