Add ref
for power=substation
#4106
Comments
I can at least contribute for Germany and Austria that there is no ref number for transformer houses existing / visible on a sign. |
I like the idea :) |
The issue I see (with the examples shown) is that there are many numbers on such a building. It is unclear which one should be entered as a |
Also, it would require a lot of research about in which region(s) such a reference number is usually publicly visible at all. All that sounds a bit too much when compared with the useful purpose this information may serve. (E.g. just so that it can be displayed on a map is a little thin. The question is, why would someone want to look for the ref on a map?) |
We need to be explicit that |
On at least one UK substation, the most obvious "ref" is just the OS grid reference (that's grid as in squares, not power grid). So it's just telling you exactly where it is, and at the same time uniquely identifying it. I'd need to check a few others to see if that's universally true. |
I think it's a company thing. SSE near me have clear names and refs, GTC in Scotland seem to also have names and refs. This one should probably be a name, not ref. I wounder if there would be any point asking for an operator, or if that's just a UK thing. |
Western Power Distribution also show clear names and references for their substations in the UK. |
@davidpnewton In the old EM Electricity region older substations will have two refs (usually separated by a slash). I checked with a friend who has worked on the distribution network for 40 years and one is the older East Midlands reference format 99A999 with the second being the 6 digit Western Power one. Examples : 52D0061/880820 , 52D1521/880309. I of course have numerous examples photographed too. |
@SK53 now that explains something. Around here they're 42D #### rather than 52D ####. I've seen instances where both that style of reference and the 6 digit one which corresponds to the Western Power Distribution ones found in the open data release they've made are present. I've also found ones where only a 4 digit reference is actually visible on the substation itself. I'd guess that each of those should really be prefixed by 42D but that for whatever reason that wasn't put on the plate on the substation. The lodge near 52D0061/880820 has always bemused me. Obviously at one point it was right in place and context as the grand entrance to Wollaton Park, but it just looks so utterly anachronistic now being separated from the remains of the grounds by such a distance and indeed the ring road. Haven't been to the area for a while now, but I know Nottingham well. |
@davidpnewton the 42D & 52D parts are indeed area codes of some form, so I think your surmise is correct. Presumably there's enough documentation only using the old codes to make it useful for maintenance work (my informant said that he's still got GPS co-ordinates of many pole-mounted substations on his Satnav). Off-topic on the lodge, but read the historical note here. It explains much of the incongruity. |
OSINT and geo-localization? |
fault reporting, ... |
I'll try to explain why the last picture is still not very complicated. "РТП" is an abbreviation of "Распределительная Трансформаторная Подстанция" (Distribution Transformer Substation) in Russian. For a Russian speaker, "ТП" is an understandable abbreviation. And seeing the number after such a reduction, it is clear that we are talking about the substation number. Other abbreviations are also understandable for a Russian speaker: the phone number (by prefixes тел..=tel., voltage - 6 kV) "B-1" is a little more complicated, but seeing the РТП, you no longer need to look for other numbers. But do not think that only abbreviations are used. Sometimes № is explicitly indicated, and sometimes it is not only inscriptions in paint, but also special plates. It is clear that there will be difficult situations, but this quest is no more difficult than entering the address of the house. And here I smoothly lead to the application of information about the Substation buildings in courtyards usually have the same address as houses + a suffix with a letter + a suffix with a subbuilding number. And it is quite difficult to write this address in osm and use it for someone. Therefore, the bases of electricians rely on the numbers of substations. Moreover, such a ref is more unique than an address, because it is unique within the service operator, which can serve several cities. Basically it's like a quest with fire hydrants, but the hydrants don't even have an address. #3059 Also, we should select only those countries/operators that use only numeric refs. (They tried to tell me about such an operator in the French matrix chat https://matrix.to/#/!fdQuIPZzzMzrCiZONx:matrix.org/$dzoKGH2g0BX1RU1z-f3CqEu-Po1haAEnLM7gf_OSnrM?via=matrix.org&via=tchncs.de&via=tedomum.net) But it seems there are not many such countries:( p.s. Do not hesitate to clarify my wording, perhaps I have translated something incorrectly or do not know many regional peculiarities. |
Looking at https://commons.wikimedia.org/wiki/Category:Distribution_substations_in_Russia and given
it seems believable to me that it is mappable, though there is a real risk that reality turns out differently and quest may need to be removed. Though I am not fully sure about actual use of this data. But
is not so outlandish use, I heard about companies maintaining hydrants using OSM data to locate hydrants because official data is incomplete/missing. Though not fully convinced. |
Removing feedback request as it was provided but still I am unsure here. I am undecided how to judge whether "РТП" is common enough abbreviation and how likely is that people will enter not Overall I would lean toward rejecting, but not really sure. |
Is it an option to add the quest and make it disabled by default? |
I am going to reject this quest suggestion because it would be difficult to ascertain for users whether "some number" / "some letters" on a substation would be the ref, or something else. There could also be several numbers on it, or none. |
FYI, this quest (in even more generic form) has since been added to SCEE (see Helium314#531) |
General
Affected tag(s) to be modified/added: ref power=substation
Question asked: What is the number of this substation?
Yard substations usually always have a number that you can see on it.
Examples
Wiki example:
![Service_building](https://user-images.githubusercontent.com/25708359/173343039-c787f030-4abd-485a-863e-cbfdf0eec52d.png)
ref=160
ref=4939
ref=329
Estimating the number of objects using Russia as an example
30916 ways
18707 ways
60% of such substations are suitable for the quest
Checklist
Checklist for quest suggestions (see guidelines):
There are renders that show these numbers. https://frexosm.ru/power https://openinframap.org (I've seen a few more global renders, but I can't remember the links yet)
While I know what to answer if the plaque is missing or damaged. This can happen with any quest.
Almost all yards have their own unique number
power=substation + building=*
since the transformers are hidden inside the building."
p.s. So we already have a dangerous quest about measuring the width of the road, which is asked for highway=secondary :)
Ideas for implementation
Element selection:
power=substation
+building=*
withoutref
orname
Perhaps you can also select
power=substaion
+man_made=street_cabinet
There may be some tags to skip (
substaion=?
location=?
voltage>=10000
)Metadata needed:
The number plate scheme should work in Russia, Ukraine, Belarus... and other ex-USSR countries.
Proposed UI:
Simple number entry field
