Does it really matter to a multi-million volt lightning strike whether
the ground is 300 ohms or five? The difference would seem to be
Just a guess here........Could it be that the low resistance required is to
allow the tower to bleed off the charge easily and thereby reducing the chance
of a direct hit? Is there anybody out there who is more of a tech than I am,
who would know for sure?
There is also a saturation effect. One or two ground rods, no matter
what the resistance reads, may not be capable of dissipating the energy
in a lightning strike.
Remember the USS Liberty (AGTR-5)
