New ERACS Documentation Facility Version 3.5.1 : Feature 2807 12/12/2005

An option has been added to ERACS that enables one or more documents to be selected and attached to any element in a network or network. The documents are presented in a list and controls are provided to manage this list. Provided that the document has been associated with a Windows application then it is possible to open the document from within ERACS.


Protection Stability Option Version 3.5.1 : Feature 2738 12/12/2005

This tool compare the setting of each protection device against the loading current calculated by Loadflow. All devices that have failed the stability check will be shown flashing on the network diagram and a control panel is displayed listing the devices. Facilities are provided that enable you to adjust the settings of a device.


Improved Data State Control Version 3.5.1 : Feature 2033 12/12/2005

After a library key has been edited ERACS asks whether elements that use the key should be updated. Prior to this release, regardless of whether the library key affects Loadflow results, if the data state had results or child data states, one was required to create a new data state. This behaviour has been modified such that ERACS does not require a new data state if the library key does not affect Loadflow results.


New Graph Option Form Version 3.5.1 : Feature 1310 12/12/2005

A tab labelled "Graph" has been included in the Options form, available from the Tools menu. This tab provides controls that enable you to select the colours used for the lines displayed on the various graphs/charts.
