Latest program version : WinIGS 7.6t - June 27, 2022

New Features in Present Version

High Resolution Display Support.  A number of user selectable options have been added in version 7.6t, which support very high resolution displays, such as larger toolbar icons and pop-up dialogs.

Enhanced Mutually Coupled Lines Model Editing. Conductor parameters and positions can now be edited in CAD-style edit window, showing line cross-section view.

User Specified Boot Resistance.  The permissible values of Touch and Step voltages now optionally take into account the user specified boot resistance and human body resistance.

Soil Resistivity Measurement Interpratation.  The RMS error and the measurement residuals are now reported in the Wenner and Schlumberger data analysis functions.

Batch Mode GPR Analysis Enhancements.  This analysis function allows you to simultaneously select any number of neutral or ground nodes and perform maximum GPR analysis on each of the selected nodes in Batch Mode.  The analysis results are tabulated in a pop-up dialog and also automatically stored in a CSV (Comma Separated Values format) file.  The tabulated results include Fault current, Split Factor, Earth current, Local GPR, Ground Resistance, X/R ratio at the fault location.  With version 7.6h, the tabulated results also include maximum touch and step voltages, permissible touch and step voltages, and the overall safety margin.

Enhanced Equipotential Polygonal Frames.  Equipotential plots can now be rendered with continuous smooth color maps for better hot spot visualization.  Furthermore, these color maps are automatically stored and can be used in EDIT mode as a guide for grounding design improvements. Equipotential polygonal plot frames can automatically conform to existing fences or polygonal lines, or become circular with user defined radius and center point. While repositioning equipotential polygonal frame vertices, markers appear on both sides of the edited vertex 3-feet away from the frame perimeter line.  This feature facilitates setting the frame boundary 3 feet away from fences or other structures so that touch voltages are computed within the appropriate regions.  (NOTE: A similar feature has been added to the horizontal polygonal ground conductor element). With version 7.6h, polygonal equipotential frames can be created and/or modified while in EDIT mode in order to facilitate batch mode touch and step voltage evaluation. The Resolution Limit in polygonal equipotential frames was increased from 512 to 2000.

Soil Resistivity Analysis data (Wenner, Schlumberger, and Driven Rod method) can now be exported in imported from CSV format files.

Ground Editor Element Selection.  Selection by rectangular area can optionally include elements crossing into selection window.  This option is activated by holding down the Shift key while dragging the mouse pointer to define the selection window.  It is also activated if the mouse stroke is from lower right to upper left direction.  Furthermore, while selecting multiple elements using the Ctrl key, now permits de-selecting a selected element.

Automatic Connector Creation.  A new command in the ground editor automatically creates a slant conductor connecting two existing conductors at the shortest distance points.

Single-Line-Diagram Voltage and Current Display.  Network view can now display up to five voltages end currents at each node and terminal.

Conductor Library.  I-Beam shaped conductors are now supported in the conductor library (Non-circular conductor category).

Case File Path Display.  The complete file path can now be display on each view frame top, instead of the file name only.  This option is selected in the General Options dialog window, under the GUI tab (Screen Group, checkbox “Show Complete File Path”).

Fault Current Analysis Updated.  The fault current analysis command output is now much more compact.  New options were added allowing selection of file format and content.

Improved Ground rod in GEM model accuracy for cases where the GEM resistivity is higher than the soil resistivity.
