This is not a proper tag for peoples driveway. It also blocks proper routing.
Don't confuse owner with access.

This tag would only apply to fenced off areas with locked gates.

Date is variable, depends on how much snow there is. That's why these winter closed roads only have a moth.

It could be moved out from a relation now yes. At the time I originally mapped it, the station only included the north part and thus the north building was partially the outer way. Didn't bother moving it out from the relation and just changed the fenced area when they expanded the station.
Things may change as they continue to renew the station. A relation might be needed still as there will probably be a physical separation of regional (66-132kV) and transmission section of the station in the future. The TSO, Statnett, will most likely only be responsible for the 420kV part later on.
It's happening all over Norway as stations get upgraded and changed due to new regulations.
Statnett is basically taking over responsibility for anything 300kV and above, unless 132kV is the highest, like in som northern parts of Norway.

To explain a bit more. The south building contains an indoor compact gas insulated switchgear for both the 66kV and 132kV grid. The north building had the old 66kV and probably some 22kV switchgear inside.
The old one is afaik going to be removed along with the old outdoor 132kV to make room for a new 420kV outdoor switchgear.

This is actually wrong. A substation is an area and anything inside it is part of this station.

Do not use Bing aerials i Norway! If this "Map builder" can't use the Norwegian Orthophoto then it can't be used here.

Source on this? Last I checked NVDB it was tagged as 582

Ezri imagery shows it nearly complete. Hydro Quebec states construction was completed in 2019 and Romaine 4 is scheduled to begin production in 2022.

Make sure you remove the source and date on the part you modify. The Kartverket N50 is imported data and the date is when that data was created/modified by them. It is no longer valid after you've modified it.

Please stop adding random photo links of things like a stream. You're also going in on someones private road and property taking picture of their homes.
Did you ask for permission from the owner before publishing it?

Ahh, passar med highway=footway + bicycle=yes då tenker eg. Den er tross alt bygd og ikkje oppstått naturleg?

OK, i see what you've done. When they branch off a single phase with neutral you tag it as 14.4kV.
Its all good, ignore my ignorance :)

Mixing line to line and line to neutral will make things rather confusing.

Why did you tag all distribution lines as 25kV when they are in fact 14.4kV?

Sette delar av denne vegen som path blir feil då dette er ein traktorveg og ikkje ein naturleg sti. Det vil også hindre sykkelruting på ei nasjonal sykkelrute. Kan ikkje fikse dårlege ruting motorar med å tagge feil. Set track type til mellom 3 og 5 så kanskje det hjelper.

Det er jo appen sitt problem at den ikkje prioriterer fortau osv

Please undo this. Short closures should be handled in the nav apps via traffic messages. This will only create a mess if the app updates rarely and happens to take a snapshot of the OSM db during the closure.

Don't do this. Its a short temp closure. It will mess up nav apps that do not update often. I'd say a road closure over months is ok, but this will probably last a couple of weeks or so.

Classification is based on the number and owner in Norway so this is kind of wrong. Four digit roads are secondary roads.
I do agree that this is a valid exception though

Don't waste time on roads named "vei" or "veg" with a number at the end. As I said they are temporary, and you'll have to go back later and update again when the final name is decided.
