Feeder Load Overview Tab
The Feeder Load Overview tab provides feeder load data for the feeders that were selected when the Feeder Load Management window was initiated or updated (either from the Viewer or the Feeder Load Summary window).
In real-time mode, the Feeder Load Overview displays:
• Present measurements: Date/Time column values in green.
• Custom forecasts (for example, 72 hours of forecasting at 30 minute intervals): Date/Time column values in black.
• Daily peak forecasts for custom FLM forecasting intervals: Date/Time column values in blue.
In Study Mode, the Feeder Load Overview displays current study session data calculated by the Feeder Load Management tool based on the user's request from the Viewing and Modifying Study Session Parameters.

To select columns to display, follow these steps:
1. Right-click the table header row and select Select Columns... from the context menu. A list of the columns is displayed.
• Selected columns are displayed in the table.
• Deselected columns are displayed in the Additional Columns balloon.
2. To add a hidden column to the table view, select the check box next to the column name. It will no longer appear in the Additional Columns balloon.
3. To hide a column from the table view, deselect its check box. It will appear in the Additional Columns balloon.
4. Click OK.
Note: If you want to save these columns settings so they will be used in future sessions, select User Preferences from the Web Workspace Preferences menu, and then click Save.
Viewing the Limiting Device by Phase
To view the limiting device in the viewer, right-click a Feeder Load Overview row and select from the View Limit Device Phase option for the applicable phase (for example, View Limit Device Phase A) from the context menu. Viewer 1 will focus on the device.
Starting a Study Session for Selected Row Profile
Each row in the Feeder Load Management window corresponds to a specific network condition. By selecting Study Session for Selected Row Profile from the right-click context menu, you can go directly into the Power Flow Study Mode Load Scenario to begin a study session in the Viewer based on the conditions in the row.
