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.

Where did you find the distribution voltage for this area? The voltage regulators on the distribution lines in the area says 7620V which would mean 13.2kV L-L voltage.

Please don't mess with the bus stops in Norway. They are updated automatically and we dont use the public transportation tags. Many of them don't even have a platform so the public_transport=platform tag is wrong.

Har no fiksa alle valideringsfeil i området. Ver så snill å ikkje lag meir krøll er du snill.

Trur du må stoppe og redigere landcover til du forstår relasjonar og kan bruke desse. Du er på veg å rasere heile området med masse feil.

This is not a 420kV transformer. It is connected to the 300 and 132kV and has a third winding at 17kV that used to be connected to some capacitor banks.

That voltage may not be accurate. The AC voltage after converting from DC to AC is never 1:1. That is why I removed it in my edit. You have to ask the operator or manufacturer as this will vary from station to station. The most common to use is 0.636 as the average and 0.707 for RMS. So most likely the voltage is around 500kV, but it still purely guesswork.

There are different school of thought here unfortunately. Some want a value for every possible tag instead of using a default value if missing. Tagging with every key and value available in OSM will lead to a lot of tags per object.

Probably because you used Bing aerials. Those are not to be used in Norway as they usually have a bad offset. No idea what imagery is available, but in iD the Norway Orthophoto is default and best option.

I just called the ferry operating the route to clarify. The Gudvangen-Kaupanger ferry no longer go via Frønningen or Styvi. It also only operates 1. May - 1. September. From 2024 there is a separate ferry Kaupanger-Frønningen. Styvi is served via the electric passenger ferry between Gudvangen and Flåm.

It is the same service. Fjord1 operates this in summer months. AFAIK the ferry still calls at Frønningen on request. Same with Styvi. It seems as though there is a separate ferry Kaupanger-Frønningen these days. Maybe more appropriate to update the existing route as there are not two separate routes here.

Adding bicycle=designated on a cycleway is pointless tag bloat. It's implied via highway=cycleway Tags like this could get removed via a validator we use here in Norway.

This is a duplicate of the already existing ferry line. The ferry go via Frønningen if needed.

Du har blanda produksjon og effekt. Fennefoss er 9,5 MW. Produksjon har ingen tag i OSM.
