You can generate inside plant diagrams, using a Custom Query Builder diagram type and data tables stored in your geodatabase.

Zoom in to the substation (situated at the end of the network at the bottom left corner of the diagram window). Click the Decrease Symbol Sizes button to change the size of the symbols for a better view of the network. Click the Select Schematic Elements button and click the Substation to select it. Right-click the substation. The inside plant diagram opens in a viewer window.

Note: You can identify elements in the inside plant diagram using the Identify tool.

Because the diagram elements are dynamically linked to the map, you can select an element in the diagram and locate it on the map.

Click the Select Schematic Elements button and click one of the primary lines on the right of the substation. Click the Propagate Schematic Selection To Map button. Click Bookmarks on the main menu, and click Substation 08 to locate the selected line. Drag the viewer windows used to display the Substation 08 and Feeder 411064000 diagrams for a better view of the line selected in the map.

Clear the selected features on the map. Remove the Feeder 411064000 data frame. Do not save the layout. Remove the Substation 08 data frame without saving its layout.
