Girdling

[TheJed]

When grounding conductors are run through metallic conduits or metallic clamps are used, you get the result of girdling.
Does this pertain to unshielded ground conductors? What if the ground conductor is shielded. Isn't this essentially the same thing with a conductor inside the shield that's inside a metallic conduit? Would it be double the girdling effect?

Any reference to unshielded or shielded wert girdling?

Thanks

The issue of increased impedance for a single conductor of an AC system only occurs where that single conductor is run through ferrous materials. Shielding is not a ferrous material.
