Isn't access=customer a bit pointless for the Instavolt hub? All stores and services would be this by default.

This would be different for a parking lot where parking is only for the store or mall customers.

I think iD has a key you hold to disable snapping completely. I rarely use iD as I got used to JOSM early on.

I just put cables in a general area and try to keep them as far away from any road or sidewalk as I can without spending to much time on it.

In JOSM it is easy to disable items with specific tags to avoid messing with them by filtering. So if I do roads I can set an inverse filter for "highway" and then only ways with that will be active. I do the same when mapping power infra.

Please don't attach power cables/lines to roads. Pay attention to snapping to other objects.

All tunnel=flooded canals should render as a tunnel on the map and that is normal.

Got links to the ways that are on surface?

You going to revert or do some else have to do this? Big changes like this need to be discussed first.

Unless its a penstock the tunnel=flooded should be used

Thanks for pointing this out, I've fixed the tags now. Not sure what happened here as its been years. Might have been some copy/paste mistake at one point. The toll point changed direction back in 2020 as well, so may have been something there.

You need to provide proper changeset description. One letter or number is not acceptable.

Why did you change this? The motorway end sign is inside the tunnel.

Welcome to OSM. Please don't start with buss routes as they require route relations. They are not as easy to do as regular elements. I have reverted both of your edits because of many mistakes.

Should add that you can clearly see in images that the low side on the transformer is on the west side as the cable tie drops into the duct along the wall. If this was a 420/3000 transformer it would have both the high and low side terminals being big.

Statnett is currently planning to build a new station roughly 500m WSW of the old one to allow for 420kV and line upgrades.

Public documents by Statnett and aerials at norgeibilder.no that we can use in OSM. Latest image will be the one shown for the preferred layer in iD. The images clearly show the 420kV line drops down to the compact switchgear and then into the reactor at the back of the bay. Statnett applied for a new 300(420)/132 transformer back in 2020. In that doc it listed two 300/132 transformers and two reactors present. The 160MVar reactor and compact switchgear has been there since the station was built I believe. At least as long as the 420kV line has existed.

Only way to know for sure is to contact Equinor directly, but I'm not sure they would respond to such a question.

Cable rating and actual operating voltage is not the same. I believe they landed on 33kV to avoid having to do heavy modifications on the platforms. Space is already limited for power handling. It seems they landed on JDR Cable Systems to provide these 66kV cables. They are designed to break if there is a problem with the mooring of the turbines to avoid pulling on the rest.

It is most likely 33k internally and then transformed to 66kV for the cables to the platforms. No wind farm I know use more than 33kV from each turbine due to size of equipment. The generators are often 690V and then a transformer at the base ups this to 33kV.

Most articles quotes 33kV that I could find. Maybe that is just the internal cabling while the cables to the platforms are at 66kV.

Where did you get the transformer rating for Skagerak 4 transformer? Also DC voltage does not equal AC voltage after conversion.

Ahh, probably the classic left hand not knowing what the right is doing. I've seen varying values used for varying companies and documents even if it is essentially the same.
