  • Electrical induction device with contact arrangement for electrically contacting an electrical conductor
    Patent number: 11769618
    Abstract: An electrical induction device includes a housing and a contact arrangement in the housing of the electrical induction device for electrically contacting an electrical conductor. The contact arrangement includes a conductor tube, a receiver contact which is fastened to the conductor tube and configured to receive and electrically connect with the electrical conductor, and a resilient suspension arrangement fastened to the housing and connected to an outside of the conductor tube such that the receiver contact is resiliently movable in a plane which is parallel to a cross section of the conductor tube while being substantially immovable in an axial direction of the conductor tube.
    Type: Grant

  • High voltage shielding device and a system comprising the same
    Patent number: 9167731
    Abstract: A high voltage shielding device including a main body having an enclosing outer solid insulating wall, an outer electrode arranged on the solid insulating wall providing a first level of insulation to the outer electrode, and a first inner electrode which is uninsulated or has a coating providing a second level of insulation, which second level of insulation is lower than the first level of insulation. The first inner electrode is oriented relative the outer electrode in such a way that the first inner electrode mainly shields a component of an electric field which is perpendicular to a component of an electric field mainly shielded by the outer electrode.
