Difference of voltage between power=circuit and its members

• power=circuit & power=line member of the circuit should have the same voltage.
• power=circuit & power=substation member of the circuit should have the same voltage.

Does it make sense ?

No, power circuit should have a voltage lower or equal to the one of its members. A 400 kV designed line can support a 225 kV circuit permanently Fanfouer (talk) 14:00, 8 October 2025 (UTC)

A portal should be in a substation

Resolved: unneeded

Or "detect portals outside substations"

It is possible to find portals outside substations: when conductors are attached between legs, it's not power=tower, it's power=portal.
So no need to enforce a validation rule for this one.

Proposal : line_management=cross should not be on end node

Resolved: done

line_management=cross is supposed to explicit that two line sharing a common support are not connected. This seems to have sense only if the lines on the support are not ending on this support, otherwise it is not possible to understand the crossing concept. So I suggest to raise a warning if line_management=cross is located on end node of a line.

A section dedicated to line_management analysis could be also created.

Proposal : line_management=split must be at end node

Resolved: done

line_management=split means a change of topolology in the number and direction of circuit. It explicitly design a break on a power line way. Thus this should be also topologically coherent, such tag should be only present at a end node of a line way, not as intermediate node.

Proposal : line_management=termination and line_management=transition must be at end node

Resolved: done

If a line terminates, or makes a transition, this must be also topologically the case. So theses tags can be only on an end node of a power line, minor_line ou cable.

location:transition=yes need to be combined with line_management=transition

Resolved: It should be combined with line_management in all cases and possible values are transition, branch, split

In some case, people use location:transition=yes but not line_management=transition

Transitions aren't the single situation in which we use location:transition=yes. Splits and branches also applies for that. Fanfouer (talk) 18:52, 16 November 2025 (UTC)
