UPDM und CP-Schaltungserfassung

<\/HEAD>

Im Rahmen unserer geplanten Migration zu UPDM und Utility Network möchten wir unsere CP-Schaltungen als Teilnetzwerke modellieren.  Derzeit haben wir eine Feature-Class namens "Insulated Node", die als willkürliche Barriere für eine CP-Schaltung fungiert.  Wie würden wir das bei unserer Datenmigration modellieren?  Ich sehe keinen entsprechenden Knotenpunkttyp in UPDM, es sei denn, ich füge vielleicht einen neuen Asset-Typ zu Electro Stop hinzu (derzeit ordnet unser Migrationsprototyp Schweißendisolatoren diesem Subtyp zu).  Irgendwelche Vorschläge?<\/P><\/BODY><\/HTML>

Good morning Mark,

Here are a few suggestions that I hope will help you with your modeling of CP systems within the Utility Network and UPDM 2018.

1) Keep in mind that the Utility Network similar to the geometric network cannot have two assets occupy the same position in coordinate space. In the case of the Utility Network that means two assets with the same X, Y ,Z coordinate. If your Insulated Node feature is to locate the same location as a coupling, then you will have issues.

2) The UPDM model manages insulated fittings and insulated devices through attributes.  Specifically on the PipelineJunction featureclass and the PipelineDevice featureclass there is an attribute called: InsulatorDevice.  This Yes/No boolean field defines where the assets acts as a cathodically insulating device.

3) When modeling CP systems with subnetworks, you will want to create a separate Tier Group from the Pipe tiers. Then you will want to create a Tier under the new Tier group.  I usually name my Tier group: Cathodic Protection, and then name my Tier as CP System.

Hope that helps
