How to Ground a Barbed Wire on Top of a Fence According to IEEE Standa

How to Ground a Barbed Wire on Top of a Fence According to IEEE Standa

How to Ground a Barbed Wire on Top of a Fence According to IEEE Standa

(OP)
I am trying to properly ground a fence in a substation according with the IEEE standards.
The fence is a 6 ft. high all-conductive fabric with over 20 years old. The fence includes 1 ft. high of barbed wire strands. Does the barbed wire have to be bounded directly to the ground wire that runs to the ground grid? Or, is the fence fabric good enough to work as a conductor according to IEEE standards? (Any IEEE standard, but I am emphasizing in std 80-1986)

Generally every few posts there is a tap off of the ground grid that runs up the fabric to the the barbed wire.  It is connected to the mesh,posts, and barbed wire with mechanical connectors.

If the barbed wire needs to be connected directly to the ground cable, on what section of IEEE standard can I base my answer?

RE: How to Ground a Barbed Wire on Top of a Fence According to IEEE Standa

IEEE 80-2000 mainly discusses whether a fence is grounded to or grounded separately from the main grid. Sounds like you've made this decision. Reference is made to the NESC (IEEE C2-2002)for the details you're asking for.

You might check with someone like Burndy to see if certain of their YG-series hydraulic-compression connectors have IEEE-837 qualification for bonding bare-copper cable to galvanized fence wire.

IEEE-80 does not specify the details of fence grounding, but section 17.3 gives guidance as to whether or not to ground it.  Our standard fence grounding details include extending #2 AWG copper ground wire up to the barbed wire and connecting to each strand with Burndy Type KSU split bolt connectors.

One reason that substation fences are grounded is to increase safety in case an overhead line falls on the fence.  For this reason, it is most important to ground the barbed wire because this will be the first point of contact with a fallen wire.

See the enclose discussion regarding the interpretation of the NESC (ANSI/IEEE Std C2)regarding grounding and bonding fence barber wire.

I hope this could help.
