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…

Hello there! Are you sure the 33kV-to-110kV transformer is ref T101? That sounds more like a code for a 10kV-to-110kV transformer…

Aha, good catch! There's also the case of the one in Rathgoggin that definitely got replaced with a bigger kiosk inside the fence, but retained its old ref number (this one: node/11076129393).

I think it makes sense that there are just two transformers inside the building, but it's considered a single station? I noticed something similar the other day (way/106564946) where there are two different names and ref numbers (which I unfortunately failed to memorize or record) on the door.

Hello! Looks like it was put on the map over ten years ago: changeset/15524207
Seemingly at the time it was showing up on Bing? I don't know, perhaps the previous editors made a mistake…
Anyway, you're right, it's not on any imagery now, so I guess the node can be deleted!

Gotcha, thanks for the info! Indeed, I think I realized my mistake with the minor/major distinction pretty soon. Did I miss some that I had misclassified?

The abandoned / demolished concept makes a lot of sense, I should have realized that sooner…
