Course Description

The CYMGRD software is a substation grounding grid design and analysis program specially designed to help engineers optimize the design of new grids and reinforce existing grids, of any shape, by virtue of easy to use, built-in danger point evaluation facilities. User-friendly data entry, efficient analysis algorithms and powerful graphical facilities render the CYMGRD software an efficient tool that helps the engineer arrive at technically sound and economical designs. The CYMGRD software will be used along the course.

Course Objectives

  • Understanding the objectives of the grounding system
