A system for transmitting data and power downhole includes an annular groove in a downhole tool such as a drill pipe shoulder or other tool body. A housing for an inductive coupler being disposed within the annular groove. The housing may be a metal ring or a polymeric ring suitable for downhole conditions. An annular MCEI trough may be located within the housing. The MCEI trough may comprise segments. One of the segments may comprise one or more perforations. An electrically conductive coil may be placed in the MCEI trough. The coil may comprise a transmission end and a groundable end. The groundable end may be connected to the tool body by a ground post through the perforations in the MCEI segments and the housing. The transmission end may be connected to a cable within the downhole tool through the other perforation in the MCEI trough and housing.
