After configuring a data structure, users can start developing Substations' operation diagram. To make it easy to create operation Screens, Elipse Power allows that an electrical model's diagram, created in Power Configuration object, be used as the basis to import all devices to a Screen in a *.prj file. This tool uses a set of graphical libraries capable of interacting with a data object, which is distributed with Elipse Power. The main function of a Screen Importer is to generate the first version of a Screen, because a few adjustments might be needed.
