How to associate a ElectricLine with a StructureJunction?

Hi Everyone,

I'm working on a project for the implementation of a Utility Network for an electric company, and they have a requirement to have the conductors separated by poles. For example, between three poles, they have two separate conductors.

The problem is that sometimes they need to be able to execute a geoprocessing task and find the line associated with the pole. Can I create a rule to register this association, or do I need an ElectricJunction at every pole to have a StructuralAttachment between the ElectricLine and the StructureJunction?

Best Regards,

Helder Medeiros

@helderhelder - The Electric Line cannot directly be associated to Pole (Structure Junction) directly. You can read about feature restrictions here - https://pro.arcgis.com/en/pro-app/3.3/help/data/utility-network/feature-restrictions.htm

 

The idea is that you would use the geometric coincidence to connect the electric line and electric junction.

You would then create a structural attachment between junction and structure junction.

In Utility Network, once this association is created you can view this without running geoprocessing tools.
-The Pole shows the structural attachments. 
-The Pole will also show the supported Subnetworks (multiple subnetworks are possible). 
-You can also synthesize the association geometries (shown in dotted green lines)

Ideally you would create something like the below for the situation you described.

You could create the junctions manually and build the association using the Modify Association tool. 
You could also create attribute rules to do this. Some inspiration here - https://www.esri.com/arcgis-blog/products/utility-network/electric-gas/advanced-attribute-rules-crea...

It might look something like - 

1) When a line is created next to a pole, find the closest point on the line to the pole. 
2)Create an Electric Junction at the point. 
3) Create structural association between Electric Junction and Pole

It is as you have said. Because you cannot directly attach an electric line to a pole you will need to create an electric junction at every pole that doesn't already have a junction or device attached to it. If you have a device or junction already attached to the pole, and connect a conductor to that junction or device, then running a trace with the include structures option selected will return the pole.
