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.
