Hi The traction power substation proposal has been updated regarding possible values conversion=(acac, acdc, no) was moved to conversion=(ac_ac, ac_dc, no)
This was a concern raised in private discussion. Vote will begin shortly if no additional point comes in mind https://wiki.openstreetmap.org/wiki/Proposed_features/Traction_substations_extension All the best François Le jeu. 25 avr. 2019 à 18:35, François Lacombe <fl.infosrese...@gmail.com> a écrit : > Hi all, > > I wrote this proposal focused on power conversion in traction substations. > > https://wiki.openstreetmap.org/wiki/Proposed_features/Traction_substations_extension > > It is proposed to use a new key conversion=* to indicate which kind of > power conversion operates inside a substation. > As explained in rationale, no voltage=* nor frequency=* can be used as > reliable information to deduce it at the substation scale. > conversion=no explicitly means no power=converter device will be found in > the substation perimeter (for instance, high speed lines modern 25kV AC > traction systems) > > This is an occasion to improve Paris railway substations mapping which > expose a few different situations > 63 kV AC => 1500 V DC > 63 kV AC => 25 kV AC > 225 kV AC => 25 kV AC > > Feel free to add opinions and concerns in Talk page > > All the best > > François >
