GEMI Analysis Research

Steel conduit reduces electromagnetic fields by up to 95%, effectively shielding computers and sensitive electronic equipment from the electromagnetic interference (EMI) caused by power distribution systems. Steel conduit is also an excellent equipment grounding conductor and complies with the requirements of NEC® 250. 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 attributes of steel conduit. The research results were published in the reports shown below and led to the development of the GEMI (grounding electromagnetic interference) Analysis Software program, also available for free download below.
