The master library is always the first project listed in the workspace primary window whenever PSCAD is started. It contains most of the components required to build almost any circuit. To open the master library, simply left-click the title in the workspace. The main master library canvas will open (Schematic window), giving access to all of its components.
Components stored in the master library are categorized into several modules (located on the main page), according to the functionality of the component. For example, all transformer components are stored in the Transformers module. In addition to these categories, most master library components are also located on the main page. Some users may find this format allows for easier navigation to the correct component.
NOTE: Component definitions stored in the master library can be viewed, but not directly modified. If you wish to modify one of these definitions, copy the definition into another library project and rename it first..
If you want to add any of these components to your own case, simply copy the instance directly from the master library and paste it into your own project. You can also use the Models tab on the ribbon control bar or the Library Pop-up Menu system.
