of course me me "drive it in with your bare hands" thus compliant
here, as in so many areas, the resistance is normally so high one cant help but wonder if it s a lot of worry for nothing.
i don't have any literature to back this up, but i believe(and know i could be wrong, i cannot find good published material on lightning related to this) ground electrode resistance is relative and should be viewed as relative to the location.
what i mean by this is the less impedance a path has
compared to the other options the current has the better. (you want lower impedance on the GEC compared to others, and relativity comes in here, the other paths are more resistive because of the "resistive" soil.)
so 20 ohms in what we call "resistive soil" may be exactly as good as 5 ohms in what we consider "conductive" soil
i believe most people visualize lightning somewhat as travelling along a conductor, while i visualize it similarly in a way but more of a emphasis on current flow of a battery. and relatively lower soil resistance changes the characteristics of the battery.
again no good proof though, but if someone would point me to published literature telling me otherwise, i would appreciate it
p.s. i know grounding electrode system is not a lightning protection system. this idea(pretty much pulled out of my a** theory) also applies to transient voltages although i know someone will say it doesn't.
