<< 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.
Added the following Schneider Electric moulded case circuit breakers (MCCBs, 1, 1) and trip units... - MCCBs: NSX100H, NSX160H, NSX250L, NSX400H & NSX630H. - Micrologic Trip Units: 2.3, 5.2, 5.3, 6.2 & 6.3
Facilities have been provided that enable you to display a symbol at the start, end and join of a connection. This makes it much easier to identify the direction of signal flow and where joints in connections occur. To change the symbols, select Tools>User Options>Connections.
It is now possible to perform a harmonic impedance survey, where ERACS will calculate the harmonic driving point impedance at every busbar in your single-line. Facilities are provided to display impedance curves and export the driving point impedance values for analysis outside of ERACS.
A facility has been added that enables you to adjust the width of the lines used to represent the electrical current value for fault lines, load lines and discrimination lines. To adjust the line width select "Program Options" from the "Tools" menu and the new control is provided on the "Appearance" page and is named "Width for Fault Line, Load Line and Discrimination Line".
Two new library export formats have been provided... 1, 1, 1) Web formatted data table: this method presents the selected library data in a tabular format, which may be viewed in any web browser. 2, 1, 1) XML document: this method will export the library data using XML (Extensible Markup Language, 1, 1), which can be viewed in most web browsers and programs that can read text based files.
Added the following Lawson fuses: types: MES, NS, J, N&T, SS, semiconductor and motor circuit.
We have made it much simpler to attach protection devices to a cable and transmission line. As well as selecting the point at which the cable attaches to a busbar, one is now able to select items that are attached to a cable.
Added Cooper Bussmann fuses; NH Series Class gG/gL, 690Vac, 2 to 800 Amps, Sizes 000 to 4.
The default option for transformer "Impedance Units" has been updated from "pu on rating" to "% on rating".
Added overcurrent and earth fault models of Fanox's SIA-C relay.
A new block has been added that enables a 2D lookup table to be defined. The purpose of the 2D lookup table is to provide an approximation to a function of the form Z = f(X,Y, 1, 1), using a lookup table method.
Overcurrent and earth fault models of Schneider Electric's Sepam 20, 40 & 80 series relays configured with time delay in "TMS mode" have been added to our reference library.
The ERACS common interface now includes the following network properties... - Appearance settings. - Result settings. - Voltage Levels: colours & thresholds.
The help system has been updated and converted to PDF format. Access to the resulting document is provided from within the calculator.
Facilities have been included that enable you to define the default value that for the protection co-ordination reactance selection. This is achieved by selecting "Program Options" from the "Tools" menu and then the "General" page. A dropdown list has been provided that allows the default value to be selected.
Added overcurrent and earth fault models of ABB's Relion (RET, REF & REM, 1, 1) 620 series relay.
Synchronous machines have been provided with an option that enables them to control the voltage at a remote busbar (i.e. a busbar that they are not connected to, 1, 1) during Loadflow studies. Please view the associated demo movie for further information.
The ERACS common interface has been updated so that it now supports text items.
An option called "Highlight Device in Single-line" has been added to the popup menu displayed when you right-click a curve. When that option is selected the single-line diagram focus is moved to the area containing the selected device, the device is highlighted and if necessary the setting graph is moved to one side.
The Arc Flash Risk Assessment module has been updated in-line with the latest 2015 edition of NFPA 70E, Standard for Electrical Safety in the Workplace.
Four new export formats have been added: 1, 1, 1) PDF document (*.pdf, 1, 1). 2, 1, 1) Scalable vector graphics (*.svg, 1, 1): this method produces an interactive diagram that is viewable in most web browsers. The resulting SVG file can be given to your clients who will be able to view and interact with the diagram as well. 3, 1, 1) Web formatted data table (*.htm, 1, 1): produces a tabular representation of your network data, viewable in most web browsers. 4, 1, 1) XML document (*.xml, 1, 1): produces a hierarchical description of your network data, which is viewable in most web browsers and text editors. Access to the existing export formats (*.bmp, *.emf, *.csv and *.jpg, 1, 1) has been made much simpler, where we have provide three ways to access the facilities: - Select "Export As" from the "File" menu. - Select "Export As" from the diagrams right click popup menu. - Click the speed button that has been included in the toolbar. Please view the associated demo movie for further information.
