Entering Model Attribute Values
The Enter Model Attribute Values dialog box allows you to edit a set of attributes for the model edit you are placing. The dialog box is opened automatically when you choose a Prompt option or you may open it for a Temporary Generator that has been added to the model.
Note: To edit attributes for a temporary generator, select Edit Attributes... from the Control Tool's Model Edits... menu.
Once you have made changes to the attributes, click OK to place the model edit or click Cancel to abort the model edit.
Repredicting Upstream/Downstream
You can force the system to manually repredict a predicted outage either upstream or downstream from the current system predicted device. This is typically done when a crew finds that the problem is not at the predicted device.
• If the device is energized, the problem is actually one or more downstream outages.
• If the device is de-energized, the problem will actually be upstream.
Clicking the Repredict Upstream button manually repredicts the outage to the next predictable upstream device. Clicking the Repredict Downstream button manually repredicts the outage to downstream devices based on outage prediction rules. When repredicting downstream, the system distributes the event to one or more devices. If a specific configuration rule (regroupAfterManualMoveDownstream) is disabled, then Repredict Downstream will manually repredict the outage to the next predictable downstream device(s) instead of using outage prediction rules. Once a predicted outage is manually repredicted upstream or downstream, it will be made stable (see “Working with Stable Predictions”). Specific configuration rules (movableAfterManualMove and stableAfterManualMove) can change whether the repredicted outages are made stable or non-movable.
Note: See “Using the Event Management Rules Tab” for information on how administrative users may set rules.
For example, a crew finds that a predicted service outage (indicated by the "PSO" symbol) at a transformer is not actually where the trouble is located. Using the Control Tool, you can repredict the outage upstream to the switch. When you repredict the outage, the switch displays a PDO (predicted device outage) symbol. The original predicted service outage displayed in one of Work Agenda's Trouble Events list windows changes to a predicted device outage located at the switch.
Creating Momentary Outages
You can create a momentary outage by simulating a momentary interruption in the system. Momentary interruptions occur when a recloser operates and does not lock out. The Create Momentary… button is only enabled on Control Tools opened from reclosing devices. To create a momentary outage, complete these steps:
1. Open a Viewer and load the map that contains the device that you want to create the momentary outage for.
2. Double-click the device. The Control Tool opens.
3. Adjust the date and time, if necessary.
4. Click the Create Momentary… button. A dialog box opens.
5. Enter the number of momentaries. Values between 1 and 100 enable the OK button.
6. Click OK. The momentary outage displays in the Work Agenda window with a status of M‑CMP.
Using Aggregate Device Actions
The Control Tool's aggregate device actions operate multiple devices with a single action. These actions are only available when the devices have been modeled for aggregate actions. When modeled, the Control Tool's Operate... function has a Secondary Device Actions submenu with the aggregate actions.
Note: The actions can still be performed separately when aggregate actions are possible.
Using the Look Ahead Dialog Box
The Look Ahead dialog box provides information concerning the results of performing a requested device operation. The Look Ahead dialog box uses system status and topology tracing to "look ahead" of the requested operation and determine its consequences.
The Look Ahead dialog box displays whenever you attempt to perform an action that would result in the distribution system status or topology changing (that is, a switching operation). Once you have looked at key information in the Look Ahead dialog box, you may perform or cancel the operation.
