The CYMGRD software is a substation grounding grid design and analysis program specially developed 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 make the CYMGRD software an efficient tool that helps the engineer arrive at technically sound and economical designs. Program Feature The use of the CYMGRD software allows for the rapid analysis of various design alternatives to choose an economical solution for any particular installation. The program conforms to IEEE 80™ 2000, IEEE 81™ 1983 and IEEE 837™ 2002.
