Guests may only view features, to also view fixes made to this version please login.

Features:

Default Folder for New Projects option Version 3.11.0 : Feature 7289 10/06/2021

Facilities have been added to the "System" page of the "Program Options" window that will enable you to define a folder that ERACS will automatically select when you create a new database.


Harmonic Injection Python Interface Version 3.11.0 : Feature 7283 10/06/2021

Our Python interface has been extended to include our Harmonic Injection calculation. That means the calculation can be automated / scripted using Python, allowing multiple simulations to be performed and analysed outside of the ERACS environment. Documentation can be found via the associated link below.

Earth Symbol for Shunts Version 3.11.0 : Feature 7279 10/06/2021

Shunts that employ our fixed impedance or admittance models and have their zero sequence data defined will have an earth symbol attached to them in the single-line diagram.


Updated Reference Library Version 3.11.0 : Feature 7276 10/06/2021

Models that represent a number of Prysmian 33kV, single core, copper, XLPE, lead sheathed cables have been included in our reference library.


Harmonic Injection Results Version 3.11.0 : Feature 7225 10/06/2021

The following results are now available for presentation on your single-line diagram...

  • Current / Voltage (% of Fundamental)
  • Current / Voltage (pu)
  • Fundamental Current / Voltage (kA/kV)
  • Fundamental Current / Voltage (A/V)
  • Fundamental Current / Voltage Angle (°)


Autosave Facility Version 3.11.0 : Feature 7163 10/06/2021

An autosave facility has been included. You will notice a small window will appear at the bottom left corner of your single-line diagram. That window includes an option to enable autosaving of modifications (data, graphical or calculation results) made to the single-line diagram. By default, the option is turned off, but it is very simple to turn on - simply "tick" the option in the aforementioned window. If enabled, every minute (the polling time can be adjusted) ERACS will check whether modifications have been made and save them. Should you prefer to disable display of the autosave window, then options are provided to disable its display.


Transformer Symbol Version 3.11.0 : Feature 6527 10/06/2021

When adding a new transformer to the diagram and then rotating it, one can sometimes forget which winding is winding one and therefore not be too sure about its orientation. To help, when adding a transformer, winding one is now drawn with a bolder line than the others. In addition to that, an option has been included in the "Network Properties" window that enables winding one of all transformers in a single-line diagram to be highlighted.


Arc Flash Risk Assessment module updated to support IEEE Std 1584-2018 Version 3.11.0 : Feature 6489 10/06/2021

The Arc Flash Risk Assessment module has been updated in line with IEEE Std 1584-2018. ERACS enables you to define multiple enclosures at each location, including their dimensions and electrode configuration. The Arc Flash Risk Assessment module then uses that information to calculate arcing currents, incident energy and arc flash boundary for each enclosure by implementing the equations defined in IEEE Std 1584-2018.
