The Main Menu contains the menu items you will need to manage and navigate through the different features of the Application.

You can enter text into the 'Search' text box to locate an item, within the treeview, whose name at least paritally matches the entered text.

You can limit the number of Equipment Containers (Line Sections, Substations, ...) within the Treeview on the window by selected a State within the 'State Filter'. When a State is selected, then only those Equipment Containers assigned to that State are included in the Treeview. Setting the 'State Filter' to 'Filter' removes any filtering and all known Equipment Containers will be included/displayed in the Treeview.

The treeview of Line Sections and Substations is the interface you use to locate, sort/order and gain access to Line Sections, Substations and Line Section Equipment Containers. To alter the sort order of these Containers you can drag n' drop the Containers. When dragging you will see either an outline region around an item, or see a horizontal line between items where you are allowed to drop. Dropping on an item will move the item you are dragging and add it to the list of items Contained by the item on which you dropped. Dropping on a horizontal line between items will move the item from where it currently resides and insert it where the horizontal line is displayed. I.E. you can re-order Line Sections.

The example below will move the '101 Redding - Red Bluff (230kV)' line section and insert it between the 'NV Line (115kV)' and the 'NV to SDG&E Line (115kV)' line sections.

Line Sections can be created, modified and deleted using the Treeview list of Line Sections and Substations.

There are two ways to create a new Line Section:

You can edit a Line Section's properties via the 'Edit' menu item on the Treeview's context menu.

You can run the Reports from the Treeview's context menu.

For information about the different reports see the Reports help page.

You use the clipboard to 'Cut', 'Copy' and 'Paste' Equipment Containers. When doing so all of the Equipment, and their specifications, are also copied to/from the clipboard.

You use the 'Delete' menu item on the Treeview's context menu to delete an Equipment Container. When you delete an Equipment Container all the contained Equipment is also deleted.
Warning: The Application does not support an 'Undo' capability, so please use caution when using the 'Delete' functionality.

Field name	Usage
Description	The name / description of this piece of equipment. To edit this value simply click in the desired cell and begin typing.
Location	The location/Substation/Terminal (i.e. Red Bluff Substation, PCG Border Terminal, ...) where the Equipment is located. The list of possible locations from which to select comes from the End-Points associated with the owning Equipment Container, as well as the possibility for more generic locations like 'Line' or 'UG Cable' (meaning the equipment is simply part of the Line). To edit this value, use your mouse to drop down the list of possible locations and select one of them. You can also set focus into the cell and use the Up and Down Arrow keys on your keyboard to locate the desired value.
Action Levels	The calculated thermal ratings of the equipment. There exists one column for each Action Level. These cells are not directly editable. They are calculated values associated with the Equipment's specifications as entered in the 'Equipment specifications area' on this window.
Notes	This column is used to indicate whether or not the equipment has any associated notes. If it does, then the column will contain a small 'I have notes' icon . If it does not, then the column will be empty. This cell is not directly editable. It simply indicates if there as any note associated with this equipment. The Notes are entered in the 'Equipment specifications area' of this window.
Work Order #	You can assign a work order number to each piece of equipment. This can help in tracking your planning and replacement of equipment. To edit this value simply click in the desired cell and begin typing.
In-Service date	The date on which the equipment did, or will, go in service. This, along with the Calculate Limiting Factors as of date enables you to do historic and future planning of Line Sections and their capacities. Double clicking on the In-Service date will set the 'Calculate Limiting Factors as of' date to the In-Service date on which you clicked. This makes for easy navigation when doing historical referencing or future planning of Line Sections and Substations. To edit this value simply click in the desired cell, then click in the down arrow within the cell and select a date from the calendar.
Out-of-Service date	The date on which the equipment did, or will, go out of service. This, along with the Calculate Limiting Factors as of date enables you to do historic and future planning of Line Sections and their capacities. Double clicking on the Out-of-Service date will set the 'Calculate Limiting Factors as of' date to the Out-of-Service date on which you clicked. This makes for easy navigation when doing historical referencing or future planning of Line Sections and Substations. To edit this value simply click in the desired cell, then click in the down arrow within the cell and select a date from the calendar.
Approved By	Each piece of equipment can be marked as 'Approved'. The name of the user that was logged in when the equipment was Approved will be listed in the column. This cell is not directly editable. Its value is set when you click on the 'Approve' button, and is cleared when you click on the 'Unapprove' button (see the next section for information on these buttons).
Approval Action	If the equipment has been Approved, then this column will contain an image with a checkmark. Clicking on this checkmark will remove the 'Approved' status on the equipment. If the equipment has not been Approved, then this column will contain an image with a cross/X. Clicking on this 'cross' will mark the equipment as 'Approved'. 'Approving' the settings for a piece of Equipment by clicking on this button will assign the currently logged in User as the person that approved the equipment settings and their name will appear in the 'Approved By' column.

Color coding is used to help quickly identify a variety of equipment statuses and values. Please refer to the images below to see how these colors within the list of Equipment relates to the user customization options that are available via the Preferences window.

When a Line Section Equipment record is selected, the Equipment specification area is filled with the detail data/specifications for that Equipment. You can then edit the data/specifications and save the values via the 'Save Changes' button. If you decide to restore the prior values, before you click the 'Save Changes' button, you can click the 'Undo Changes' button to refresh the data entry fields with the equipment's previous values.

The context menu associated with the list of Equipment allows a number of operations to be performed on the Equipment.

This area contains data entry fields associated with the selected Equipment's specifications that are used when calculating thermal ratings. The entry fields will be different for each different type of equipment. For more information see Equipment Types.

There is a checkbox entitled 'Use Precalculated values' within this section. If you wish to override the calculated values, you can check this box and then enter the pre-calculated value you have for each Action Level. For Equipment Types that, by default, require pre-calculated values this checkbox is not visible and you simply enter the Action Level values.

The 'Nomenclature' field is included for reference and future enhancements. It is not currently required and is not used in any reports.

The display parameters area of the window allows you to customize how you want the data associated with the Line Sections, Substations and Equipment displayed:
