Re: [TCML] dogkennel faraday cage?



I'll send a detail if I can find one. All fences on my industrial jobs were grounded. Most had no details, but merely notes. All corner posts and line posts every so many feet were grounded, and the same BIG bare copper grounding cable also was bonded to the fabric, top and bottom posts, and all three strands of barbed-wire. I understood that when they were located under 115 kV power lines, but never quite understood the purpose, unless a boom truck or crane outriggers were to come in contact with the fence while lifting a piece of equipment, to keep their frames at the same potential.

Pics of an industrial fence?

At work, we ground all fabric, then using the same cable, bond the posts and top and bottom rails, so they make electrical fittings for this.

   The phrase Faraday Cage has come to have multiple meanings.
   As an arc/spark catcher, I'd think what's described would work.
   Things to be wary/aware of, in my experience:
    top and sides are mentioned, needs a BOTTOM.
    Grounding is semi nonrelavant, so long as continuity
    between the wires is maintained.
    Which raises another thought:
     Usual 'chain link fence' does not guarantee electrical
     continuity.  Effective faraday cage requires
     continuity.
    Some level of continuity is required at 'edge':
     wall corners, walls to roof, walls to
     floor/bottom.

For effective emi/rfi control the electrical continuity
aspects become more critical, and careful, designed handling
of ALL wires passing thru the wall.  (details on request...)
