From ERICO brochure
"IEEE std. 142-1991 recommends system resistance values of 1 to 5
Ohms." (perhaps others have access to the relevant sections and how
they apply to towers)
142's title is IEEE Recommended Practice for Grounding of Industrial and
Commercial Power Systems
It's divided into separate sections on "what do do with a structure" ,
"what to do with specific manufacturing processes", and "how to connect
it to Earth"
For instance, there's stuff about dusty areas (flour mills and bakeries,
for example)
It doesn't say much about towers, per se.
