Hi Jherome, This mail to give you some news about "transformer banks" tagging in OSM.
I've completed the proposal started last Febuary https://wiki.openstreetmap.org/wiki/Proposed_features/Transformer_extension_proposal There is a chapter dedicated to transformers sets, which sounds to be a better name for what we use to call banks https://wiki.openstreetmap.org/wiki/Proposed_features/Transformer_extension_proposal#Transformer_sets Let me know if you have any remarks As far as I know, this won't get in conflict with existing tagging. The document only extend things and make them more precise regarding of how transformers work.
