Tag:power=connection

The tag power=connection is used for a free-standing electrical connection between two or more power lines or cables, known as power segments. It is intended for connections occurring elsewhere than on a power support (tower, pole, portal...).

We can sometimes find several overhead lines connect with no supports: the tag power=connection is required for such situations to clarify that the power lines are connected and electricity can flow between them and to prevent any quality warning about non power nodes on power lines.

Connections can also occur on supports like power=tower, power=pole or even at line terminations/in substations.
You should look at line_management=branch or line_management=transition to map this.

How to map

On every free-standing power connection between two or more lines (mapped as power=line or power=minor_line) or cable place a node shared by all connected ways and add power=connection, and additional optional tags as appropriate:

Tag	Value	Description	Recommendation
power	connection	It's a free-standing power connection linking two or more power segments	Mandatory
operator operator:wikidata	operator	The power connection operator's name.	Recommended
line_management	Management values, usually branch	The line management applicable to each connection	optional
cables	amount of cables	The amount of cables involved in the connection. On 3-phases systems it's possible to distinguish individual cables and use cables=1 on each connection.	Optional
