Move Transformers

This tool allows you to move both tapped and inline transformers from one location along a line to another location, with just a few clicks. It also gives the option to move other associated features, like secondary lines connected to a transformer.

IMPORTANT: This tool does not support Z-values.

When secondary lines are connected to the low side of the transformer, you are given the choice to move the secondary lines as well. The secondary lines maintain connectivity with both the services and transformer, and they “stretch” to accommodate the transformer’s new position.

Moving Transformers

To move a transformer, first select the transformer you’d like to move, then click the Move tool, which enables snapping to valid line features.

Click once on the target line to select the location of the tap point. After the first click, an offset line automatically appears showing the offset distance configured in Solution Center for TransformerToLineRadiusInMapUnits (refer to the Electric Domain topic in the Solution Center configuration guide), as seen in the image below. This automatically offsets the placement of the moved transformer from the line feature.

Click a second time in the location where you’d like to place the transformer.

TIP: If the move you are making requires you to move the transformer outside of the configured offset, hold the spacebar to temporarily turn off the locked offset and place your feature where you wish.

If there are secondary lines attached to the transformer you are moving, you are notified of these and asked if you want to move them as well. Click Yes to include them in your move, or No to leave them as they are currently placed.

IMPORTANT: The secondary line is redrawn from the target location to the vertex closest to the origin of the original transformer location. Thus, mid-span vertices in secondary lines may result in a new secondary line that is not straight.

Trace connectivity is maintained for both the new and old locations when a transformer is moved.

As mentioned above, transformers that are moved to a location with a different phase from its original location are automatically updated to the phase designation of its new location. Secondary lines and other features associated to the transformer that move with it also have their phases updated accordingly. Connection points created when moving a transformer are always created with all phases.

Eligibility (Can I Move This Feature?)

Be mindful of this prerequisite prior to using this tool:

This tool supports transformers that are either the E:Transformer — Tap or E:Transformer — Inline network category.

If a feature is not supported, this tool is not present on the Component Information pane.

How to Move a Feature

To move a feature, follow these steps:

Zoom and pan reasonably close to the feature you want to move. In your map extent, you can see the new location where you are going to move the feature.
Send the feature to the Component Information pane. There are a couple ways to do this:
1. With the ArcGIS Pro Select tool, select the feature. Then, in the Component Information pane, click the Load Selected button.
2. In the map, right-click the feature, then choose Component Info. This automatically sends the feature to the Component Information pane.
In the Component Information pane, click the Move tool.
In the map, click the new location for the feature. While the tool is active, the cursor snaps to features according to your Utility Network snapping rules.
TIP: Click Esc to cancel the tool.
- The tool automatically determines the gap distance between the two line ends at the original assembly location and recreates the gap at the new location.
  
  TIP: Assemblies can’t be moved within a certain distance of an existing vertex or other feature, since the tool automatically creates a gap in the line.
- The tool moves the line ends, the assembly, and the contained units in the electric device feature class.
- Containment associations remain intact, while maintaining connectivity.
- At the original location, the gap is repaired, but a split in the line remains. Connectivity is maintained at the original location as well.
- If the transformer you’re moving has connected secondaries, an additional dialog appears asking if you want to also move the connected secondaries.
After the edit processes, run the Validate tool to clear any Utility Network dirty areas.

Common Move Notifications

When moving tapped transformers, there are a few scenarios that display a Move Failed notification instead of successfully moving the transformer. The notifications are described in the tables below.

E:Has Connected Units	Details/Notification
Phasing is derived from units PhasesNormal attribute.	Transformer must contain at least one unit (junction object).
	Must have a junction-junction connectivity association from both high & low terminals to each of the units.
	Device terminal configuration path field must = "None."
	Transformer must be tapped and NOT connected to the high side terminal.
On phase change, both units and device PhasesNormal attribute are updated.	This addresses UN tracing issues when device phasing doesn't match/include unit phasing.

E:Has Disconnected Units	Details/Notification
Phasing is derived from device PhasesNormal attribute.	Transformer must contain at least one unit (junction object).
	Device must NOT have connected units.
	Device terminal configuration path field must = "All."
	Transformer must be tapped and NOT connected to the high side terminal.
On phase change, only the device PhasesNormal attribute is updated.	Unit phases aren’t updated since network flow isn’t affected. You have the option of using an AU/AR to keep unit records in sync.

No Network Category	Details/Notification
Phasing is derived from device PhasesNormal attribute.	Transformer must be tapped and NOT connected to the high side terminal.
Number of phases must match target conductor phase. The move doesn’t happen if the phases don’t match.
On phase change, only the device PhasesNormal attribute is updated	Units are not allowed without the E:Has Connected Units or E:Has Disconnected Units category.
