Making One‑line Diagrams

Starting a New One-line

Click New on the Quick Access Toolbar on the top left of the EasyPower window (toolbar menu: File > New > One-Line). EasyPower opens a blank one-line in the Database Edit focus so you can start creating a new one-line. By default, EasyPower names the file “Oneline1” (or 2, or 3, and so on). You can easily change the name by clicking Save on the Quick Access Toolbar (toolbar menu: File > Save or File > Save As) after you have placed equipment on the one-line.

Tip: You can also perform these commands from the button on the top left corner of the window.

From here, creating and editing a one-line diagram is a simple matter of choosing the desired power system equipment from the equipment palette, and then placing it on the drawing. If you place the item's leader on a bus, EasyPower automatically connects the equipment, or you can drag the item to the bus with the pointer.

Save and Save As

Save your file often to avoid losing your work. The first time you click Save on a new one-line, the Save As dialog box is displayed so you can select the directory and file name for the file. The file name can be up to 256 characters long, including blank spaces. After you have performed an initial save, any subsequent saves you perform are automatically stored. If you want to save the file under another name, use Save As to select a new directory or name.

Open and Close

To open a file that has already been created, click Open on the Quick Access Toolbar (toolbar menu: File > Open). This displays the standard Microsoft Windows Open dialog which allows you to search through drives and directories to find the file you want. Open the file by either double-clicking it or highlighting it and then clicking on OK.

If you are working on a network and someone else has already opened the file you want to use, or the file properties are set as "read-only," you only be allowed to open the file as read-only. This means you can view the file but not save changes to it. You can use > Save As to store the file under another name or in a different location.

To close a file, click Close in the upper right-hand corner of the one-line (or on the Close icon if the window is minimized) or click > Close.

Menu bar

When using the toolbar style, the menu bar provides you with links to common tasks and the various focuses.

Equipment Palette

In the ribbon style, the Equipment Palette enables you to add AC or DC equipment and notes ("Annotations") to the one-line. This is similar to the Equipment Toolbar, and the symbols for both are the same. While you are editing the database, the equipment palette provides the necessary equipment types to create a power system one-line diagram.

You can hide or show the equipment palette using the right-click context menu.
