Power preset additions for transfomer and power plant

[Gazer75]

Original claim:

Could we get the the rating and windings added for primary, secondary and tertiary on transformers?
​https://wiki.openstreetmap.org/wiki/Tag:power%3Dtransformer#Tagging

I'd also like to see a box for owner on power plant menu. The owner and operator of such facilities are often not the same.

Following the approval of ​​https://wiki.openstreetmap.org/wiki/Proposed_features/Transformers_classification_refinement, it would be great to add the following changes as well please:

• Discourage transformer=traction, transformer=auto, transformer=minor_distribution
• Carefully replace transformer=distribution when installed in an actual substation (an area with power=substation on it) - low priority
• Update pole with transformer preset with transformer=distribution or transformer=main (currently only with transformer=distribution). transformer=auxiliary isn't covered as it comes with other significant equipment (switches mostly).
• transformer=auxiliary is no more restricted to power=substation perimeters and can be used standalone as well (probably no change in JOSM validation).
• Create transformer=main ​https://wiki.openstreetmap.org/wiki/Tag%3Atransformer%3Dmain
• Create windings:auto=yes ​https://wiki.openstreetmap.org/wiki/Key:windings:auto

I am not sure if all these subtags are suitable for defaultpresets, for now, especially the ones with low numbers in use.

Maybe, an external preset hosted on this wiki is a better solution for these special tags with low numbers or if only "in use" or "proposed" but not "approved".

[skyper]

Still only low numbers.
owner=* is ignored, so far, and is worth an own ticket as it is not tied to power tagging.

Dear all

It's true power transformers tagging is expert stuff and could confuse most of osm mappers.
We could at least improve the power=transformer preset with windings:primary and windings:secondary beside windings=* that must remain in the preset.

However, this ticket should be paused until this proposal has been voted. A few details remain to be fixed but it is almost done.

+1 for owner=* on different ticket (and valuable for any power=* asset, not just power plants).

Best regards

[skyper]

The vote will end today and it looks like the proposal will be accepted.

[francois.lacombe]

Yes, the current proposal was accepted :)
Thank you Skyper for your support

I can update this ticket (once documentation completed), or create a separate one if you mind.

Final changelist is:

• Discourage transformer=traction, transformer=auto, transformer=minor_distribution
• Carefully replace transformer=distribution when installed in an actual substation
• Create transformer=main
• Create windings:auto=yes

We'll be able to add transformer=compensator as proposed by Gazer75 once documented too.

See #21836 as well for additional deprecation.

All the best

[skyper]

Updating this ticket is OK, I guess, and #21836 can be fixed along side.

[francois.lacombe]

Good Skyper, ticket was updated and wiki is up to date :)

[francois.lacombe]

I've updated the description : I forgot to mention the pole with transformer preset.

Best regards

Hello,

Am I mistaking release r18597 that closes this ticket?

[taylor.smock]

r18597 does replace transformer=traction with transformer=main, replaces transformer=auto with windings:auto=yes, and adds transformer=main. It does not "[carefully] replace transformer=distribution when installed in an actual substation".

[francois.lacombe]

Thanks Taylor for follow up

Unless it can be achieved with common rules, we could drop this point.
It's not necessary to introduce specific Java code for it, there are more urgent topics.

Best regards

[taylor.smock]

We could try using the ∈ mapcss operator, e.g.

*[transformer=distribution] ∈ area[power=substation] {
  throwWarning: tr("{0} inside {1}", "transformer=distribution", "power=substation");
}

But I don't map power infrastructure all that often, so I have no clue if that would be the correct warning. It wouldn't automatically replace the node, but it would bring attention.

[francois.lacombe]

I wasn't aware of such operator in mapcss. That's great!
It sounds like the right rule for areas and it can be completed with incompatibility between substation=* and transformer=distribution on the same node.
See ​https://wiki.openstreetmap.org/wiki/Item:Q7682

It wouldn't automatically replace the node, but it would bring attention.

That's perfectly fine

Cheers
