Use Electric Utility Network Foundation

The Electric Utility Network Foundation solution provides a preconfigured asset package, maps, styles, step-by-step instructions, common data management workflows, and more.

In this topic, you will learn how to use the solution to create and manage your electric utility network. These workflows will use the asset map and utility network geodatabase that can be created from the essentials asset package in the Configure utility network environment topic. These are a guide to help you learn key workflows in the Electric Utility Network Foundation solution.

Perform network traces

Tracing is a key capability of the utility network. In the following workflows, you will perform several types of traces.

Locate upstream protective device

A common task is to find the first upstream protective device from a location. The location is typically where an outage or fault has occurred and will often be a known transformer. In this workflow, a protective device is any device that can be automatically operated to break a fault. This includes a fuse, recloser, elbow or circuit breaker.

1. Open the Electric Unbalanced Distribution Essentials ArcGIS Pro project.
2. In the Map tab, in the Selection group click Clear.
3. In the Catalog pane, expand the drop-down arrow next to Maps.
4. Double-click the map configured in the Configure utility network environment topic that uses the provided sample data.
5. In the Map tab, in the Inquiry group, click Locate.
6. In the Locate pane, click the Layer Search tab and in the search box enter the ID of an overhead transformer, such as MV-XFR-189 if using the sample data, and hit Enter.
7. Right-click the identified transformer and click Add To Selection.
8. Click on the Selected Features in the lower right corner of the Map pane until this feature is visible.
9. In the Utility Network tab, in the Tools group, click the drop-down arrow under Trace and click Starting Points.
