Microshocks from induced voltage

MG
Has anyone ever come across the requirement to earth a section of metallic fence to mitigate micro-shocks that may be induced by an overhead transmission line? I have looked online but there is no methodology or guidance value listed other than just "earth the fence".


Any info would be useful.


Thanks

    HI Mike (MG) 


    I think - if I remember correctly what we were trying to achieve was to allow an equi-potential to from and between everything so that in the event of an HV fault, everything rises and falls in potential as evenly as possible. (Between HV/train/metal fencing/building structure etc etc.) 


    Induced voltage may have been a small consideration but I don't really remember if it was the main point of Bonding?


    Sorry I think I should have used the term bonding on the above post and I cant edit the post.


    A very long time later ------ I've found it - here:
