Drawing a network

  • Different types of lines, cables and pipes can be drawn freely with the mouse on the graphics panel and can have any arbitrary form
  • Electrical, gas, water and heating elements can be selected from a tool box
  • Many elements are available in several different representations
  • Inserting an element a dialogue pops up, where all specific physical parameters can be defined
  • The drawn network can be copied and pasted via OLE into MS-Word or other applications
  • The physical parameters associated to an element can be copied all at once to another element

Auxiliary graphics

  • Auxiliary graphics can be used for documenting the diagram
  • It is possible to draw lines, rectangles, ellipses, arcs, ellipse sections, polygons, polylines, any kind of bitmap graphics
  • Texts with selectable character sets can be drawn into the diagrams
  • The colours for background, foreground, line, outlines and fill patterns are user-selectable
  • Functions are available for rendering overlapped symbol elements, alignment and rotation

Colouring of network

  • Colours and line types can be freely selected
  • Elements overloaded after a load flow or short-circuit-current analysis are colour-highlighted
  • Isolated elements can be highlighted
  • Colouring options to distinguish user-defined network areas, zones, feeders, voltage levels, earthed or un-supplied networks and galvanic separated networks
  • Differences to the parent variant or the root net can be coloured
  • Each element can be coloured individually
  • User defined graphic layers can be coloured
  • Colouring according to ranges. Many calculated variables can be coloured according to their values (e.g. according to element losses or according to voltage drops)
  • Colours of results in tables and graphic charts, flow animation, background visualization, gauche, pie charts can be freely selected

Symbol editor

  • The user can create and define for each element type and node its own symbols
  • User defined Symbol Libraries
  • It is possible to define more than one representation for each element type
  • All symbols will be displayed when entering the diagram. The desired symbol can be  dragged and dropped into the graphics panel
  • On the graphics panel the symbols can be flipped, rotated and resized
  • Delete. copy, move, insert, zoom and align are also functions available for symbol editing

Visualisation of networks in separate diagrams and layers

  • The visualisation of a network can be separated into several diagrams. In this way it is for example possible to show the low voltage part in one diagram and the medium voltage part in another
  • The content of a diagram can again be divided into several layers. This allows to hide or colour the content by layer
  • Zooming into stations: in one diagram an overview of all the network can be shown with the station shown as a simple box, in other diagrams the details of each single station with all its breakers, protective devices and instruments
  • Topological the elements can be linked between several diagrams
  • All diagrams will be considered for various analyses (e.g. load flow)
  • An element can have more than one graphical representation in the same diagram or in different diagrams
  • Graphical data can be imported in MS-Word or other programs with Copy/Paste (OLE)

Chart manager

  • The chart manager allows to display the results in different charts. (e.g. line, bar, etc.)
  • Any number of sub charts can be displayed in one chart
  • A user defined logo (as bitmap) can be added to the header for documentation purposes
  • Results from different variants can be compared and displayed in the same chart
  • The chart can be exported as an image
  • Copy/paste to the clipboard is possible for documentation purposes. (e.g. to MS-Word)

Multi-lingual graphical user interface

The user interface of the software is available in English, German, French and other languages.
