Restoring to Normal Mode

To place a network protector in disabled mode:

1. Open the Control Tool for the Network Protector switch that you want to update.

2. Click the Manual/Disable Mode... button to open the submenu.

3. Click the Enable NP button. Existing Manual/Disable conditions will be removed. The NP Disabled condition will be removed from Conditions Summary.

The buttons on the submenu will reflect the current status of the device. For example, the Disable button will desensitized if the device is already disabled.

The Manual and Disabled modes can also be driven from SCADA measurements. If the device has a SCADA point that indicated it is disabled, for example, then the user options to re-enable a device (or move it to manual mode) will not be available if the device is disabled from SCADA.

Placing Jumpers

In addition to creating an open point, you can insert a jumper on an overhead conductor or between overhead conductors; you can also place emergency cables between underground devices. The jumper is an active part of the model and fully operable. You can open and close jumpers as well as place tags and notes on a jumper.

Model Edits initiated from the Control Tool will be recorded as steps into a switching sheet recording Real Time actions. If no switching sheet is actively recording Real Time actions, then the action will be recorded into the Miscellaneous Log. The actions will also show up in the User Log. If the model edit fails, then the step will be marked as Failed. Model Edit operations can only be initiated from the Control Tool. Web Switching does not support initiating model edits from a switching step.

The Control Tool's Model Edits... context menu allows you to select from the following jumper types.

Jumper Type	Description
In-line Jumper	In-line jumpers are placed in line. The position for the jumper is set to "closed" to maintain a continuous conductor. A closed jumper symbol displays at the midpoint of the selected conductor.
P-P Jumper/Emergency Cable	Point-to-point jumpers are placed between a selected conductor and the same phase on any other conductor. A dialog box allows you to specify the second conductor. You can select the conductor in the Viewer. A point-to-point jumper symbol displays at the midpoints of the selected conductors. The default state for the inserted jumper is "open."
P-P Cross Phase	Point-to-point cross phase jumpers are placed between different phases on two different conductors. The Cross Phase Selection dialog box allows you to select a live phase and the phase to pick up. The Select Secondary dialog box allows you to specify the second conductor. You can select the conductor in the Viewer. A point-to-point jumper symbol displays, connecting the midpoints of the selected conductors. The default state for the inserted jumper is "open."
Inline Cross Phase	Creates an in-line cross phase jumper to correct any mis-modelled phasing. If desired, this can be configured for single and two phase fuses. The user presses this button and is presented with the standard cross phase dialog box. After choosing the live phase, the system traces upstream to find the first object downstream from a device that contains that live phase, then places an inline cross phase jumper between those two devices. This model edit is automatically removed by the system if the map is rebuilt with the corrected phase.
Tap Generator	Tap Generators are used to add an energization point to the model. A Selection Required dialog box allows you to specify the tap location by clicking on the location in the Viewer.
Temporary Generator	Temporary Generators are similar to Tap Generators, but contain attributes needed to affect the power flow solution. The Add Temporary Generator... option opens the Add Temporary Regulation Device dialog box, which allows you to edit these attributes. See Adding a Temporary Generator on page 2-120 for details.
Mobile Sub	Mobile Subs are similar to P-P Jumpers, but contain disconnect switches and a power transformer plus attributes needed to affect the power flow solution. The Insert Mobile Sub... option opens the Add Temporary Regulation Device dialog box, which allows you to edit these attributes.
