+1 substation=industrial

The question is to know which is the target of that kind of "hint" and will
everyone will understand it as such ?

You're assuming 132 kV/10 kV substation are for distribution because you
find 10 kV inside but operator can use it a way OSM won't know.

That's why I'm tagging substation=transmission each time voltage goes above
30 kV inside the substation. IMHO

I'm ok with that.
