Phase Propagator in Trace Configuration

The steps below walk you through setting up the phase propagator as required for ArcFM tracing. These instructions start at a point that assumes you already have your utility network configured. If you have not finished configuring your UN, be sure this is complete before starting these steps.

IMPORTANT: Before you apply the propagator, verify that your Network Attributes are set on the subtype group layers.

To do this, run the Geoprocessing tool called Set Network Attribute and associate the Phases Current network attribute with the phasescurrent field on each feature class.

Verify that the Phasesenergized field exists on the Device, Junction and Line feature classes. If they do not, start with Step 1. If they do exist, you can start with Step 2.

Add the PHASESENERGIZED field to the necessary feature classes.
- Electric Distribution Device
- Electric Distribution Junction
- Electric Distribution Line
Complete the following edits for each feature class listed above:
1. Open ArcGIS Pro and connect to your UN database through Catalog.
2. Right-click on the feature class in the Catalog pane and select Design > Fields to open the Fields table.
3. Click the New Field button or click in the empty field at the bottom of the table, and type PHASESENERGIZED in the Field Name.
4. In the Domain field select the ElectricDistributionPhaseAttribution domain in the drop-down.
5. Right-click the same feature class again and select Design > Domains to open the Domains table.
6. Right-click the same feature class again and select Design > Subtypes to open the Subtypes table. Find the PHASESENERGIZED domain in the Subtypes table and add the ElectricDistributionPhaseAttribution domain with Unknown set as the Default Value.
As part of the ArcFM Tracing configuration, it is required you add a network category called LoadPoint to the Service Point asset group or subtype.
1. Use the ArcGIS Pro Geoprocessing tool to search for Set Network Category. Click on the tool to launch it.
2. Click and drag the new utility network into the Input Utility Network field.
3. In the Domain Network field, select ElectricDistribution.
4. Select ElectricDistributionDevice in the Input Feature Class drop-down.
5. In the Asset Group field select Service Point.
6. Then select an asset type from the Asset Type drop-down list.
7. In the Categories field, select LoadPoint.
8. Click Run.
  
  IMPORTANT: Rerun Steps f-h on each Service Point Asset Type.
Next, you need to add the phase propagator. To add the propagator, navigate to the Analysis tab and click the ModelBuilder button.
1. Search in the Geoprocessing pane for the Set Subnetwork Definition tool. Then click, drag, and drop the tool into ModelBuilder.
2. Double-click the Set Subnetwork Definition tool and fill out all the parameters as shown below.
  TIP: Be sure to select your utility network database connection and not the service connection.
3. Your model likely looks like the model below. If the Set Subnetwork Definition and utility network elements are not colored in, it means some parameters are not set correctly or are missing.
  - To enable the tool (colors), double click the Set Subnetwork Definition element to open Set Subnetwork Definition pane. Set the parameters similar to the image in Step 3b above but change them according to your network, then click OK. A large list of Asset Types is displayed. Ensure no red exclamation marks are present.
When the model is enabled, right-click the Set Subnetwork Definition element and select Create Variable > From Parameter > Propagators. A Propagators element is added.
To enable propagators, double-click the Propagators element, select Phases Current, and click OK. Notice the Propagators element is now displayed in color.
Double-click on Propagators again, fill in any missing values as shown in the image below and click OK.
On the ModelBuilder tab, click Validate and Run to ensure the script runs successfully. You can save your model for future use if you wish.

IMPORTANT: Verify the propagator is included in the geodatabase connection by opening the network properties of the UN and check the tier definition to which the propagator was added. There is an entry under the Trace Configuration column that states the propagator's configuration. If this is missing, you need to remove the UN layer from the map and add it back in for the Geodatabase connection to include the propagator as part of your published Operational Map.
Follow the post-process steps on Esri’s Electric Utility Network Foundation. Exporting the subnetwork is an optional step.
