Hello,
We are building an underground electrical network for a windfarm. The whole system have 5 circuit. One circuit can have as many as 21 turbines each with a transformer 34.5kV/575V. The circuit have many sub-circuits that are connected in parallel to the main circuit. Transformers are...
The project is installed in Canada and there is no regulation adressing that point.
It's a 34.5 kV 3 wire delta, the bare copper is effectively installed to provide structure grounding connecting every wind turbine grid.
Hello,
We are working on a wind farm project. The collector system is underground. We use TRXLPE 1/3CN 34.5kV cable with LLDPE jacket that are placed in a flat configuration without spacing. We do install a bare copper conductor in the trench along the cable.

I found this IEEE paper on rebar in concrete as electrode. It confirms what i was assuming.http://www.mikeholt.com/files/PDF/Use_of_Conc_Encased_GR_as_GE_Fagan_Lee_1970.pdf
Marmite did a pretty good summary of what is done actually in the field. I'll get the Wind Energy Handbook for sure, documentation on wind turbine are pretty hard to find here it's fairly new.
Alehman, as for now I've worked with two manufacturer, GE and Enercon and both of them has a...
Hello expert,
I'm working on a windfarm project. We are at the stage of designing the grounding system of the windmill. Each windmill has a concrete foundation with rebar.
Assuming that
-windturbine requires a fairly low resistivity ground system
-type of soil we are working with is mostly...
