The tag building=transformer_tower represents a tall building specially designed to connect to an overhead medium voltage power line (power=minor_line) and to house a small substation with a distribution transformer. Often, the power line has been dismantled and replaced by an underground cable. However, the building may still be in use as a substation.

How to map

Map the building and add the tag building=transformer_tower.

If the building is still in use as a substation then it should also get the following tags:

Other optional tags:

  • operator=* (the name of the power company)
  • ref=*, name=* (any reference number or name the power company may use to refer to this substation)
