UFER grounds
UFER grounds
(OP)
I have, for many years maintained that electrical service grounding electrodes obtained by connecting a copper wire via cadweld to rebar in concrete slabs or footings is a superior way to provide a low impedance ground for any facility. I have used the Lyncole XIT copper pipes and they are very good but in my new heavy industrial field of work, that is not a real option. What is your experience with using UFER grounds in various soil and climate installations? If you have test results that would be good as well. Thanks in advance for your input.

I did use never the Ufer Grounding alone, but combined with a regular ground grid.
First of all is very difficult to calculate the actual Ufer Grounding contribution to the Ground Grid resistance, GPR, Touch and Step Potential. Usually we take it as a bonus only.

For large installations such as substations or powerplants, I would not rely solely on the Ufer ground, but use it as a supplement to the ground grid, as previously suggested.
