Features:

Updated Reference Library Version 3.9.7 : Feature 5482 14/07/2016

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


Universal Dynamic Modeller Version 3.9.7 : Feature 5389 14/07/2016

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.


Harmonic Impedance Module Version 3.9.7 : Feature 5382 14/07/2016

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.


Protection Coordination Graph Version 3.9.7 : Feature 5336 14/07/2016

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".


Library Export Facilities Version 3.9.7 : Feature 5317 14/07/2016

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.


Updated Reference Library Version 3.9.7 : Feature 5306 14/07/2016

Added the following Lawson fuses: types: MES, NS, J, N&T, SS, semiconductor and motor circuit.


Protection Devices Version 3.9.7 : Feature 5304 14/07/2016

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.


Updated Reference Library Version 3.9.7 : Feature 5286 14/07/2016

Added Cooper Bussmann fuses; NH Series Class gG/gL, 690Vac, 2 to 800 Amps, Sizes 000 to 4.


Transformer Impedance Units Version 3.9.7 : Feature 5194 14/07/2016

The default option for transformer "Impedance Units" has been updated from "pu on rating" to "% on rating".


Updated Reference Library Version 3.9.7 : Feature 5187 14/07/2016

Added overcurrent and earth fault models of Fanox's SIA-C relay.


Universal Dynamic Modeller Version 3.9.7 : Feature 5161 14/07/2016

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.


Updated Reference Library Version 3.9.7 : Feature 5147 14/07/2016

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.


ERACS Common Interface Version 3.9.7 : Feature 5126 14/07/2016

The ERACS common interface now includes the following network properties... - Appearance settings. - Result settings. - Voltage Levels: colours & thresholds.


Induction Machine Parameter Calculator Version 3.9.7 : Feature 5085 14/07/2016

The help system has been updated and converted to PDF format. Access to the resulting document is provided from within the calculator.


Protection Coordination Reactance Selection Version 3.9.7 : Feature 5075 14/07/2016

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.


Updated Reference Library Version 3.9.7 : Feature 5025 14/07/2016

Added overcurrent and earth fault models of ABB's Relion (RET, REF & REM, 1, 1) 620 series relay.


Loadflow Voltage Control Version 3.9.7 : Feature 4978 14/07/2016

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.


ERACS Common Interface Version 3.9.7 : Feature 4847 14/07/2016

The ERACS common interface has been updated so that it now supports text items.


Protection Coordination Graph Version 3.9.7 : Feature 4634 14/07/2016

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.


Arc Flash Risk Assessment module Version 3.9.7 : Feature 4403 14/07/2016

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.


Export Facilities Version 3.9.7 : Feature 4307 14/07/2016

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.
