Application software for analysis and design of grounding grids of substations based on the requirements of the IEEE 80 "IEEE Guide for Safety in AC Substation Grounding".  Aspix calculates the grid resistance, and touch and step voltages for grids of any shape.  The program can use uniform or two layer soil models.

Try Aspix

  • Download and install Aspix.  The installer will check for .NET Framework 4.5 before installing Aspix.  If.NET Framework 4.5 is not installed, follow the Installation Instructions for install it.

  • Download and install the complements needed to generate reports. These complements can be downloaded from the following links:
