Hierarchical visualization using Composite Views – Networks & Motors

Hierarchical visualization using Composite Views – Networks & Motors

Composite Networks allow users to model and graphically divide the network into multi-nested views all in one project. Composite Motors combine motor control centers (MCC), loads, motors, and protective devices and represent it as a single element. These different views provide a more organized and straightforward appearance. Composite Networks can be nested with unlimited sub-networks, allowing for multiple layers in one project.

  • Customizable Views
  • Unlimited Composite Views
  • Unlimited Connections
  • User-defined Location & Sizing
  • User-defined Symbols, Thumbnails, Images
  • Visualize Properties & Results
Color Contouring

Color Contouring

Color contouring functionality allows the user to apply a preset or user-configurable color map to the one-line diagram. These maps are color-coded based on voltage or power flow magnitude providing an instant picture of normal and abnormal areas of the electrical or geospatial system, especially for extensive networks.

Engineering Data Display & Management - DataBlock

Engineering Data Display & Management - DataBlock

View device information such as input data and study results in a single Datablock directly on the one-line diagram. Datablocks may be applied from templates or user-customizable. Utilize one or more single-line diagrams to show, hide, arrange, and format according to the targeted information. Extend analysis capabilities with Datablocks by showing properties and results from different studies and within the same one-line diagram.
