Electrical Grounding Analysis

SKM GroundMat is a program for substation ground grid design and analysis. It is designed to help optimize grid design or reinforce existing grids of any shape. It uses a general-purpose finite element algorithm for potential analysis and graphical facilities to validate ground system efficiency.



  • 1. Design safer and more cost effective ground grids.
  • 2. Save time with graphical entry and display.
  • 3. Communicate designs more easily with professional reports and graphs.
  • 4. Evaluate alternatives quickly and easily to establish an optimal design.
  • 5. Save time with design wizard capabilities.
  • 6. PTW GroundMat is an important tool every power system engineer should have.
