Steel Tube as Ground Electrode

Steel Tube as Ground Electrode

Steel Tube as Ground Electrode

(OP)
I have multiple foundation steel piles to be used as grounding electrodes. They each appear as a hollow cylindrical steel tube or pipe, perhaps 5/8 inch thickness, and could be driven 10-13m to solid rock. O.D is not selected, but perhaps 8-12 inch.

Has anyone seen a methodology to represent these in grounding grid calculations, perhaps even equivalent electrode methods. Otherwise, I am in for hard and tedious work developing and C++ coding of substantial calculations perhaps using methods presented by Meliopoulos. Thanks

RE: Steel Tube as Ground Electrode

These can be modeled in programs such as CDEGS by SES. http://www.sestech.com/
 

RE: Steel Tube as Ground Electrode

There is no difference for grounding between the steel piles and very large diameter solid ground rods.  If you're present analysis method can handle ground rods of different diameters, you should have no problem.
