Would be sorted like this...
  • BUS_1
  • BUS_2

Copy Existing Study window Version 3.9.6 : Feature 4757 13/04/2015

The Copy Existing Study window has been improved so that one is able to select whether the studies for all data states are displayed. This greatly reduces the information presented and makes it much easier to select studies: - A "Show studies from all data states" tick box has been added to the window. - When "Show studies from all data states" is not ticked... -- the list presents only those studies performed in the current data state. - When "Show studies from all data states" is ticked... -- All studies from all data states are presented in the list. -- The list includes both "Study Name" and "Data State Name". -- The studies from different data states are displayed differently.

The harmonic impedance module has been updated to provide facilities to export the following items to a comma-separated values (CSV, 1, 1) file...

  • the harmonic impedance angle values.
  • the harmonic impedance magnitude values.
  • the harmonic transfer coefficient (magnitude of harmonic impedance / driving point impedance, 1, 1).
Please note that we have used the term "harmonic impedance" to mean the driving point impedance for the injection busbar and the transfer impedance for all other busbars.


Protection, Harmonic Impedance & Transient Graphs Version 3.9.6 : Feature 4725 13/04/2015

Two buttons have been included in the toolbar of each of these windows. The buttons enable one to copy the graph and the window to the clipboard as an image that can then be pasted into a document of another application; e.g. Microsoft Word.
