Ground Grid & Earthing Systems
Enabling the design and analysis of ground protection. Integrate 3-D technology with one-line diagrams to visualize ground systems.
Grounding Grid Design
One-line diagrams are integrated with advanced 3-D technology, enabling engineers to design and optimize electrical ground grid systems. With full color 3-D results, engineers can visualize their ground designs and accurately determine protection and other equipment requirements.
ETAP Grounding software incorporates multiple design tools; enabling quick ground layout estimates as well as extremely detailed design. ETAP is useful for substation grounding, building grounding, 3 phase transformer grounding, and isolated field equipment grounding.
