We are testing our ground rods at out facility with a fluke clamp on meter. On some of the transformers 480/120 we get "noise" or current on the test, why is this? how can it be fixed?:-?
It is happening because there is current flowing, and perfectly normal. It can also be from improper wiring which can be fixed.We are testing our ground rods at out facility with a fluke clamp on meter.

No, the rod has to be connected to the system for any of the clamp-on ground resistance testers to work.With the Fluke clamp-on, if you disconnect the grounding electrode conductor from it's termination (panel, transformer, etc) can you measure the resistance of just that one electrode by clamping the non-terminated GEC ?.
