<< IMPORTANT NOTICE >>
Development of and support for the ERACS software product will come to an end on 21 December 2023. Please do not hesitate to contact us if you require further assistance.
Details of new features & fixes across the ERACS versions.
100 two-winding distribution transformers have been added to the reference library, increasing the total to over 150.
Additional cables have been added and the reference library now includes the following cables: 300 x 1kV, 240 x 3.3kV, 70 x 6.6kV, 200 x 11kV, 56 x 22kV, 120 x 33kV, 3 x 66kV, 7 x 132kV, 7 x 275 kV and 4 x 400kV.
Miniature circuit breakers produced by manufacturers ABB (5 product ranges, 1, 1) MEM (3 product ranges) Merlin Gerin (11 product ranges, 1, 1) Moeller (7 product ranges, 1, 1) Siemens (15 product ranges) and Terasaki (10 product ranges) are now available.
The number of fuses provided in the library has been substantially increased. Fuses produced by manufacturers such as: ABB (5 product ranges, 1, 1) AREVA (6 product ranges, 1, 1) Cooper Bussmann (59 product ranges, 1, 1) Ferraz Shawmut (4 product ranges, 1, 1) GE Power Controls (14 product ranges, 1, 1) SIBA (22 product ranges) and Siemens (25 product ranges) are now available.
Where possible cable zero sequence impedance values (R0, X0 and C0) have been set to 3 times the positive sequence values for multicore cables and 1.25 times for single core cables (Ref. J&P Switchgear Book 7th Edition).
Where possible cable entries in the reference library have been updated in line with RINA Cable Rating Reports (Ref. 69-30).
A new miniature circuit breakers (mcb) model has been added for use in Protection Co-ordination including a dedicated single line diagram symbol.
Fields have been added to the cable library data entry form to enable users to record greater information and in preparation for the implementation of cable withstand calculations. Fields Include: Cross sectional area, Cross sectional area units,. Conductor material, Number of cores, Armour, Unit Length, Insulation and Manufacturer.
The maximum number of multi-range setting ranges for both current and time settings has been increased from 5 to 10.
Three buttons have been added to the library form that enable users to clear, export and load voltage waveforms... - 'Clear' - This will clear the characteristic. - 'Export' - This will export the characteristic to a comma separated variable (csv) file. - 'Load' - This will load the characteristic from a csv file.
After clicking 'Show Data' to display data on the diagram, when an element's data is modified, the diagrammatic data being displayed is now automatically updated.
The following two options have been provided in the discrimination box's popup menu: Send To Back and Bring To Front.
A web access toolbar has been added to the ERACS control panel. This toolbar provides quick access to the following features provided by the ERACS User Site: FAQs, Downloads, ERACS Power Engineering Forum and Online Demos.
A trace facility has been added to the Transient Stability, Harmonic Impedance and Protection graphs. This facility enables users to read off more accurate values from the curves.
A wizard facility has been added to ease the acquisition of library key data when no library keys, of the element type selected from the network diagram, are present in the project libraries. The wizard steps through the process of either... - creating a new library key - copying a library key from a library of the user's choice - copying a library key from the ERACS Reference Library ...then associates the newly created/copied library key with the selected network diagram element. Please see associated movie for additional information and further instructions.
A new security solution called 'Web Access' has been added to ERACS. This solution does not use a hardware security key (dongle). Instead, we will host your ERACS licence on our Web Server and provided that you have an active internet connection, you should be able to connect to our server from anywhere in the world.
