Update Subnetwork not updating Isconnected and Subnetwork Name

Hi Team,

I am testing the new circuit where I just created one circuit breaker with Three Phase CB MV Controller Asset type then connected one Under ground connector to it . And set the circuit breaker feature as controller then ran update subnetwork . The Conductor's Isconnected and Subnetwork name are updated as Unknown .Not Sure Why , But when I a connected trace by keeping Circuit Breaker as starting , It selects the conductor features too .Not Sure what's missing here .

@MikeMillerGIS @RobertKrisher

Can any of us also help me in getting the data dictionary for Electric ?

I was using the below URL but couldn't find this

You can find the data dictionaries here - https://doc.arcgis.com/en/arcgis-solutions/latest/reference/introduction-to-electric-utility-network-foundation.htm#ESRI_SECTION1_7F90EBF29A6E451F837FF680AB23097A

As for the circuit, what terminal did you connect the connector too? What terminal did you assign the controller info on?

@KokilaM Have you populated the phasing fields of the circuit breaker and conductor? If there isn't any phasing on the breaker it won't energize the subnetwork.

Phase Normal is not set up as the propagated value in the model. Phase Change is. Phase Change needs to be defined on the controllers and any place phase deviates.

Thanks Mike , It worked after updating the phase change of attribute CB.Where can I check what value is assigned as propagated value in the model? Because when we migrate the data from Gtech , we are going to migrate the phase information to phasesnormal field .So how this going to affect the subnetwork build?

In the Utility Network properties page, in the tiers subnetwork definition, scroll all the way to the right. You can also use the Generate Schema Report tool and review it in there.

You should see something like this:
