Ground Grid Systems

The next generation Ground Grid Systems module enables engineers to quickly and accurately design and analyze ground protection.

Advanced 3-D technology integrates with one-line diagrams, enabling engineers to visualize their ground systems and seamlessly utilize short circuit results.

Flexible design methodologies allow for quick auto-designed layouts or very detailed schemes. Color-coded graphical plots provide impressive results.
