GEMI Analysis Software
Download the free GEMI Analysis Software to:
– confirm wire-type equipment grounding conductors provide an effective ground-fault current path
– confirm steel conduit and electrical metallic tubing (EMT) provide an effective ground-fault current path
– determine how steel conduit and electrical metallic tubing can shield against the effects of electromagnetic fields
GEMI Analysis Research
Steel conduit and tubing are excellent equipment grounding conductors and comply with the requirements of NEC® Article 250. Steel conduit and EMT reduce electromagnetic fields by up to 95%, effectively shielding computers and sensitive electronic equipment from the electromagnetic interference (EMI) caused by power distribution systems and other sources. Learn more about GEMI with the informative free resources below. The Georgia Institute of Technology has conducted research on both the shielding and equipment grounding capabilities and shielding attributes of steel conduit and tubing. The research results were published in the reports also available for free download below and led to the development of the GEMI (grounding electromagnetic interference) Analysis Software program. The software has been updated in 2020 with more modern technology that verified and refined the original results and data.
