UPDM e Rastreamento de Circuito CP

<\/HEAD>

Como parte da nossa migração eventual para UPDM e Utility Network, gostaríamos de modelar nossos circuitos CP como sub-redes.  No momento, temos uma classe de feição chamada "Insulated Node" que atua como uma barreira arbitrária para um circuito CP.  Como modelaríamos isso em nossa migração de dados?  Eu realmente não vejo um tipo de junção correspondente no UPDM, a menos que talvez eu adicione um novo tipo de ativo ao Electro Stop (atualmente nosso protótipo de migração mapeia isoladores de extremidade de solda para esse subtipo).  Alguma sugestão? <\/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
