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.

Features
  • Simulation of grounding grids of any shape including horizontal conductors and vertical electrodes (rods)
  • Uniform or two layer soil model
  • Calculation of grounding grid resistance
  • Calculation of maximum permissible touch and step voltage according to IEEE 80
  • Calculation of touch and step voltages within a user-defined area
  • 2D and 3D views of the grounding grids
  • 2D and 3D plots of touch and step voltages
  • Word, Excel or PDF report
