Abstract:
A system for transmitting data through a string of downhole components comprising a plurality of joined downhole components, each downhole component comprising:a first data transmission located proximate to a first end of each downhole component, which first includes a first magnetically conductive, electrically insulating trough, and a first electrically conducting coil lying therein; a second data transmission located proximate to a second end of each downhole component, which second includes a second magnetically conductive, electrically insulating trough, and a second electrically conducting coil lying therein; an electrical conductor in electrical communication with and running between each first and second coil in each component; whereby the first data transmission in one of the plurality of downhole components is cooperatively arranged to be in magnetic, but not in electrical communication with the second data transmission of another one of the plurality of downhole components, when the downhole components are joined.
