| titleOfInvention | Apparatus for electromagnetically coupling power and data signals between well bore apparatus and the surface |
| abstract | ABSTRACT OF THE DISCLOSURE In the representative embodiment of the new and improved apparatus disclosed herein, a downhole tool adapted to be coupled in a pipe string and positioned in a well bore is provided with one or more electrical devices cooperatively arranged to receive power from surface power sources or to transmit and/or receive control or data signals from surface equipment. Unique inner and outer coil assemblies arranged on ferrite cores are arranged on the downhole tool and a suspension cable for electromagnetically coupling the electrical devices to the surface equipment so that power and/or data or control signals can be transmitted between the downhole and surface equipment. |
