Details of new features & fixes across the ERACS versions.
ERACS Version 3.9.5 - Released: 27/03/2014
Guests may only view features, to also view fixes made to this version please login.
Features:
New Loadflow Result for Machines - Percentage kA Loading Version 3.9.5 : Feature 4594 27/03/2014
We have included "Percentage kA Loading (%, 1, 1)" as a displayable result for synchronous and induction machines. The value is calculated as the ratio, expressed as a percentage, of the current delivered by the machine to the rated current of the machine. The rated current is determined using the machine's rated MVA and rated kV.
Network Overview Window - Cursor Style option Version 3.9.5 : Feature 4521 27/03/2014
An option has been added to the popup menu of the Network Overview window that enables the style of the mouse cursor that appears when the mouse is placed over the viewport to be selected. Two options have been provided: Arrow and Hand.
Export to standalone Arc Flash Hazard Calculator Version 3.9.5 : Feature 4447 27/03/2014
A facility has been added to the Arc Flash Hazard Report (i.e. the results form shown after running an Arc Flash Hazard Assessment) to export the study into a format that can be imported into the standalone Arc Flash Hazard Calculator.
3000 Busbar Version Version 3.9.5 : Feature 4442 27/03/2014
ERACS now supports up to 3000 busbars. Please contact the ERACS Team should you require this option.
ABB PR512/P relay added Version 3.9.5 : Feature 4393 27/03/2014
The ABB PR512/P overcurrent and earth fault relay has been added to the ERACS Reference Library.
Library Memo Field Version 3.9.5 : Feature 4388 27/03/2014
The library memo field has been made more accessible and is now contained within the library data entry form, in its own tabbed page.
Mechanical Load library entries improved Version 3.9.5 : Feature 4383 27/03/2014
The mechanical load entries in the ERACS Reference Library have been rationalised, improving the key names and descriptions.
Network Overview Window - Improved Navigation for Large Networks Version 3.9.5 : Feature 4370 27/03/2014
Use of the network overview window to navigate large networks has been improved, especially where the network is so large that the current viewport is difficult to locate. One can now set the network diagram viewport by either double-clicking or clicking the mouse wheel at the desired location in the network overview window.
New Busbar Voltage Profile Report in Transient Stability Version 3.9.5 : Feature 4369 27/03/2014
Following a Transient Stability calculation, a busbar voltage profile report can be generated. This report displays the identifier, description, rated kV, Loadflow kV, Transient kV and voltage difference for every busbar in the network, following a Transient Stability calculation. The voltage profile report is accessed via a new button that has been included on the Transient Stability graph window or via a new option in the Results menu.
Web Access Security Failover Version 3.9.5 : Feature 4358 27/03/2014
Following an outage with our web access security solution, we have provided a software failover facility that enables ERACS to switch from our main web access server to a replicated failover server. This modification should provide a more robust and reliable security solution.
Web Access Security Solution Guide Version 3.9.5 : Feature 4352 27/03/2014
A web access security solution guide has been produced and an option to access the guide has been added to the Manuals sub-menu in the Help menu.
Fault Type Indication in Summary Results Version 3.9.5 : Feature 4248 27/03/2014
A new result option has been provided that enables you to select and then display a brief description of the fault type in the summary results box that is shown on the network diagram.
New Protection Setting Report Version 3.9.5 : Feature 4199 27/03/2014
It is now possible to create a protection setting report without having to run a protection study. The new facility enables multiple protection setting reports to be created. One is able to select whether the report contains all protection devices or just a subset. The report presents the devices in a tabular format and groups the devices by switchboard (busbar, 1, 1) and circuit (element to which the device is attached or adjacent switch, 1, 1). The table of setting can be opened in Microsoft Word with a single click and can also be exported to various formats, including PDF.
Arc Flash Labels - European and American formats available Version 3.9.5 : Feature 4070 27/03/2014
A "Label Format" facility has been added to enable generation of European or American arc flash hazard warning labels from within an Arc Flash Hazard study.
Network Property for Arc Flash Units Version 3.9.5 : Feature 3898 27/03/2014
It is now possible to select Arc Flash Units (metric or imperial) as a property of a Network. This impacts the units used for distance- and energy-related fields during study setup and when viewing results within an Arc Flash Hazard study.
