shouldn't it be voltage instead of voltages? -- Schusch 12:40, 26 November 2008 (UTC)

i correct that because i'm pretty sure -- Schusch 12:56, 26 November 2008 (UTC)

Location Aboveground/underground?

Would it be appropriate to have

  • location=aboveground added as a default value

so then if your adding the tag, you have the option of making it 'underground' In JOSM, this could be added as an option with default value. --acrosscanadatrails 10:20, 12 March 2009 (UTC)


What does one do for a power distribution substation? power=substation perhaps? -Fennecfoxen 19:02, 12 April 2009 (UTC)

Intersections with streets

I don't understand the last sentence about more accuracy by adding nodes when intersecting roads. That sounds totally bogus. 1. Why should that improve accuracy? 2. There's no physical link between roads and powerlines, they are on totally different heights, it's not possible to get from one tho the other (as a node would imply). So this is plain wrong. --Fröstel 08:46, 25 June 2009 (UTC)

Non-power lines

How to tag non-power lines, such as telephone cables? --Skippern 02:37, 28 August 2010 (BST)

No idea, but I'll riff on power=line and use telephone=line. --Hamish 09:50, 23 February 2011 (UTC)

Frequency of line

I know most of the world distributes high voltage energy as 50Hz, but at least Brazil have exemptions here, the distributed energy is 60Hz, and at least one mayor power line (Iguacu power plant near Foz do Iguacu/Puerto de Iguacu on the border between Brazil/Argentina/Paraguai to São Paulo) is DC (0Hz). Is this information that is interesting to tag, and in so case, how should this be tagged? I would hazard to use frequency=* on the power lines. --Skippern (talk) 16:59, 1 February 2013 (UTC)

The frequency=* tag is documented, also for power line use. However, the power line wiki is missing a link to the frequency tag. In northern Europe the frequency tag is widely used on power lines. For the 50/60 Hz grids (dependent on region) it may be unnecessary to use it but for example in Germany it is the way to distinguish the normal power grid from the railway power grid (16.7 Hz). frequency=0 is the standard tag for indicating HVDC transmission lines. So no problem adding frequency tags to power lines. It is especially important to use the tag on lines that use a frequency different from the default value for the region. --polderrunner (talk) 20:22, 1 February 2013 (UTC)
Frequency shouldn't be added on lines but on circuits relations involving lines because the line is only composed of conductors, which aren't designed for a specific frequency.
The operator of the line choose to operate a given line at a given frequency to transmit power according to needs. Then it's only a circuit matter and not a line one.
It have to be said that a line can be intended for a particular usage (linemen won't add a 3rd conductor for a HVDC line), but the design goes in cables=* and wires=* on power lines while the circuits relation get the frequency=* matching the operational conditions Fanfouer (talk) 15:06, 1 January 2018 (UTC)

Multiple circuits with different voltages

There appear to be no set way to tag lines that have this. I've seen quite often a mix of 66kV and 22kV on two level wooden h-frame towers. The 22kV line then branches off at times to end in a small transformer. --Gazer75 (talk) 12:15, 1 January 2018 (UTC)

You can use voltage=voltage_a;voltage_b.
circuits=* key gives the amount of circuits taking the line.
Finally, actual circuits can be mapped with relations which are not yet fully defined. Have a look to this proposal. Fanfouer (talk) 14:55, 1 January 2018 (UTC)
