If you were checking grounds in a newly developed project with new houses, what
would you use to check the grounding to each house? The fire hydrant. You
would run heavy 00 welding cable from the hydrant to each house and measure the
resistance. Out in the country you would use your well casing as your
reference and measure resistance to various points. RF as far as I am concerned
is less than 1 OHM. Electrical standards is 25 ohms or so. Every thing
radiates so you have to take other measures.
