Telecommunications Grounding

Telecommunications Grounding

Telecommunications Grounding

(OP)
Hi, I am testing Telecommunication Grounding. The electrodes are in the street. Should be possible get wrong measure because of water pipes across the street, electric lines, etc?. I have put the test rods of the Megger on the street.
I am looking forward to your response.
Thanks

RE: Telecommunications Grounding

Yes, any underground metal will have a impact on your measurements.  Also, you will not have good results using a Megger.  You need a ground resistance tester that will inject a square wave or something that can be separated from the 60 Hz and dc stray currents you may run into.  

Try to get the electrodes as far away from the buried metal as possible.
