15367	Power transformer extension	francois.lacombe	team	"Hi,

An extension proposal had been accepted regarding power transformer mapping. Both power transformer and power pole with transformer presets should be updated.
https://wiki.openstreetmap.org/wiki/Proposed_features/Transformer_extension_proposal

Tagging of power=transformer has been updated accordingly
https://wiki.openstreetmap.org/wiki/Tag:power%3Dtransformer#Tagging

User should be prompted for the following tags (with according label), out of casual ones :
* transformer= {distribution, generator, converter, traction, auto, phase_angle_regulator, auxiliary, yes} (Function of transformer)
* location=* (Transformer location)
* phases=* (Number of phases)
* frequency=* (Operating frequency)
* voltage:primary=* (Primary ""power plant side"" voltage)
* voltage:secondary=* (Secondary ""consumer side"" voltage)
* voltage:tertiary=* (Tertiary ""auxiliary side"" voltage)
* windings=* (Number of windings)
* windings:configuration = {star, delta, open-delta, zigzag, open, scott, leblanc} (Windings configuration)
* rating=* (Rating in VA)
* devices=* (Number of different transformer devices)

voltage=* key shouldn't be used any more on power transformers.

Additionally, some validation rules should be created as follow and warn users :
* Check rating=* is given in VA and without any unit in the value (like multiples kVA, MVA,...)
* Check voltage=* isn't associated with power=transformer or transformer keys

Thank you in advance to take care of this, all the best."	enhancement	closed	normal	18.05	Internal preset		fixed	power, transformer
