Cathodic Protection on transmission towers

[PanCogito]

Hi,
Is anybody familiar with Cathodic Protection Systems installed on transmission towers(lattice tower/self-supporting structures and guyed structures)? There is a problem of the level of protection required on the multi metal system(copper grounding, zinc coated steel and zinc coated anchor rods). Do you think that potential less negative than -850mV still will be considered adequate on the tower coupled with copper ground?
Thanks.

Try to ask on the NACE Forum, there is a forum dedicated to Cathodic Protection.

I'd like too an answer too. How do you overcome all the AC current?

Hi,
Good question! Where is the NACE Forum? I was trying to find it, but it must be well hidden......

NACE forums are not very easy to find....i don't know why butthey don't want to be found...
follow this links and you'll be connected with the main page, then select cathodic protection, or i suggest you also the NACE forum on the same page.
