Oops, muscle memory fail! Yes, it's a typo, I'll go fix it now!

Oh shoot, yes it is! Was so busy fixing the poles I forgot to change the tags on the cable itself!

Thank you!

Hello!

Yeah, that line flies over the transformer, it's attached to the wall for support. You can see the insulators from the Bing Streetside image captured on the bridge.

There are wires tapped off it going vertically down to the transformer though.

I'm not sure… I think actual transformers are a lot more common than these, so the risk is pretty low. But it may indeed have happened in some instances!

Hello! It's like a kiosk transformer, only without the transformer bit. It's a little box with MV switchgear inside, and it has a 6/7-digit reference code just like MV-LV transformers do.

I guess I put it as `power=switchgear` here because it was inside a `power=substation` area. I know I've mapped isolated units elsewhere as `power=substation` themselves.

Honestly I'm not sure if this was the best way to tag these (especially since iD complained when I attached the power cables to a `man_made=street_cabinet`), but I couldn't think of anything better…

You mean node/13946048816? You're welcome! :)

Hi! Yeah, because of the different offsets on newer imagery, someone had added four "trees" that were actually pylons I had already mapped.

Thinking about it now, it might have been AI-assisted...

Oops, muscle memory misfire! Normally autocomplete does that for me but I must have pressed Tab too early!

Quite possibly! I think I copied those tags from the substation itself, which is visible on imagery going back to 2013 but didn't actually start being used until 2021…

I had completely forgotten about this. https://www.kirbygroup.com/project/kylemore-way-bess-ireland/ mentions "110V DC battery systems", so I must have picked up that number. It's a bit vague though, maybe that's referring to something else in the compound…

This is the line I was referring to: way/522113928

Oops, no, that fixme shouldn't be there! It was on a different line, which I must have continued and split several times, and forgot to take it off this particular split.

I think I solved the original issue some time ago…

Thanks for pointing it out! This inspired me to go fill in a few more gaps around here just now!

Hi!

No, it's definitely 110/20 kV. I guess since it's a fairly new planned town, they built the distribution network at 20 kV from the get-go.

Hello!

Here (and at most of these "house" substations), the transformers are configured with the secondary (10-kV) bay running directly underneath the primary (38-kV) one, so I map as a single dual-circuit (and dual-voltage) bay to capture it succinctly.

I guess it doesn't fully reflect reality though, because the 10-kV line transitions underground at the wall, whereas the 38-kV line goes indoors via the aforementioned overground terminal. That's why it ends up splitting into a `power=cable` and `power=minor_line` with two different voltages at that point.

Interesting, thanks! I had noticed that there was lovely new Mapbox imagery for Cork a while back, but I don't think it had occurred to me to look for this on it… I'll have a look!

Hello! It's referring to the conductor cross-section in mm².

I added these lines to JOSM, which offered that field as part of its power line preset. IIRC I read at a later point that this and possibly a few other tags were developed by the German OSM community, and probably aren't really used elsewhere…

Ah OK, I guess it's much less complicated than I thought!

Ah, fantastic, it's from April! Believe it or not, I was just about to start looking at this again, so this works out quite well!

Thanks! :)

Oops, copy-paste error I guess!

Come to think of it, shouldn't all the 110-kV hardware in the Dublin area be marked as ESB Networks rather than EirGrid, since it's considered "distribution" there? I assume Nangor falls within that designation, since it's a child station of Inchicore (or was until Castlebaggot was built anyway)…

Morning! As far as I know it's 400 kV and then there will be a transformer at Knoxkraha (Gogganstown) to bring it down to 220kV. Not sure why, but that's what the public info seems to say...
