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...

Must be... I'm guessing I had circuits=4 on an earlier rev and forgot to change it. The real problem is that I was too lazy to map the individual circuits, which I've been meaning to rectify for well over a year now! 😦

Oops, typo! Should be guyed=yes
Thanks for pointing it out!

Hmm. I guess I assumed that the old 2-MVA T41 was (at least temporarily) wired up to the new GIS buildings, but now that you mention it that doesn't make much sense. The new 5-MVA T42 was already on-site before the old busbars were removed, so it's unlikely that the old transformers were ever connected to the new switchgear.

I need to go and have another look at the station anyway because I think it's been further upgraded since I last mapped it…

Aha, thanks for the heads-up! So the new 400-kV station is being built to the east, not in that little empty corner like I had assumed…

Hi Daniel, thanks for reaching out!

No, I'm pretty sure this pole has a recloser (automatic switch) on it. You can see on "Esri World Imagery (Clarity) Beta" that it has an elongated cylinder (the recloser itself) near the top, and then a little rectangle further down (the control panel / handle).

It's a normally-open switch separating a feeder from Lee Bridge (to the north) from a different feeder from Hartnetts Cross (to the south).

The pole you highlighted is a branch point, which may or may not have ordinary AIS mechanical switches on it, but it would be very unusual to have a recloser on a branch pole – that'd be a lot of gear to hang on a single support structure!

I hope this clarifies things :)

Best regards,
PluM

Hello! I haven't seen it up close, but from what I can make out from the aerial imagery, I think it must be. The pylon just looks like a normal end mast, and the nearby double-poles are normal suspension ones, so there don't seem to be any dedicated branching masts. From what I've seen elsewhere that seems to be the way these 110-kV branches are usually done…

Oh yes, I noticed that, I thought I'd fixed all of them! Silly iD autocompletes to steel, then changes to stone before I even realize it…
