Abstract
An apparatus for conducting alternating current through a well barrier made substantially entirely of ferromagnetic material includes at least one non-ferromagnetic electrically conductive rigid tube extending through its own separate passageway in the well barrier. A single electrical conductor carrying the alternating current, extending through the well barrier, is enclosed by each rigid tube. The electrical conductor includes insulation electrically isolating the rigid tube from the conductor.
Claims9
An apparatus for conducting alternating current through a well barrier made substantially entirely of ferromagnetic material, said apparatus comprising:
- at least one non-ferromagnetic electrically conductive rigid tube extending through its own separate passageway in the well barrier;
- and
- a single electrical conductor carrying the alternating current extending through the well barrier enclosed by each rigid tube, said electrical conductor including insulation electrically isolating said rigid tube from said conductor.
An apparatus for conducting multiphase alternating current through a well barrier made substantially entirely of ferromagnetic material, said apparatus comprising:
- a plurality of conductors for conducting the multiphase alternating current, said conductors extending through the well barrier;
- and
- a plurality of non-ferromagnetic, electrically conductive rigid tubes extending through its own separate passageway in the well barrier, each one of said plurality of rigid tubes enclosing a corresponding one of said plurality of conductors.
