Patent number: 10298005Abstract: An electrical penetrator assembly is shown, configured to feed electrical voltage and current through a wall separating a first volume and a second volume, which may have different pressure and/or may be filled with different fluids. The connector comprises a wall or partition having a through opening. An electrical conductor surrounded by a tubular insulator body passes the opening through the wall. A conductive or semi-conductive coating is arranged on the exterior of the insulator body, the coating surrounding the insulator body for a portion of its length, the coating in electrical contact with the wall, wherein the coated portion of the insulator body is shaped to displace the electric field around the conductor away from the wall and reduce the electric field strength around the insulator body by increasing the electric field strength inside the insulator body.Type: GrantFiled: August 27, 2015Date of Patent: May 21, 2019Assignee: Vetco Gray Scandinavia ASInventors: Svein Tryti, Jan Erik Elnan-Knutsen, Erik Raad, Gorm Sande

Patent number: 8282804Abstract: An electrostatic coalescing device including at least one pair of sheet-shaped electrodes arranged at a distance from each other side-by-side. Each one of the electrodes includes a sheet-shaped conductive member of electrically conductive material. The mutual distance between the conductive members of the two electrodes of the pair varies along the electrodes as seen in a direction perpendicular to the intended flow direction of fluid passing through the flow passage between the electrodes. A power supply is configured to apply mutually different electric potentials to the conductive members of the electrodes of the pair so as to form an electric field between the electrodes. The conductive member of one electrode of the pair is planar, whereas the conductive member of the other electrode of the pair is corrugated.Type: GrantFiled: May 15, 2007Date of Patent: October 9, 2012Assignee: Hamworthy PLCInventors: Svein Tryti, Peder Hansson, Pål Jahre Nilsen, Nicolai Gedde

Patent number: 7964079Abstract: An electrical appliance including at least one sheet-shaped electrode and a connecting device for electrically connecting the at least one electrode to a voltage source. The connecting device includes a casing having two or more tubular casing parts. Each casing part enclosing a channel filled with a dielectric medium, and an elongated conductor for feeding electric power from the voltage source to the at least one electrode. The conductor extends through the channels of the casing parts and is surrounded by the dielectric medium therein. The conductor extends through a hole in an electrically conductive member of each individual electrode. The conductor is electrically connected to the conductive members of the electrodes and each individual electrode has a part arranged between two of the casing parts with the two casing parts clamped against opposite sides of the intermediate electrode part.Type: GrantFiled: May 25, 2007Date of Patent: June 21, 2011Assignee: Hamworthy plcInventors: Rune Strand, Svein Tryti, Svein Jørgensen

Publication number: 20090173684Abstract: An electrostatic coalescing device including at least one pair of sheet-shaped electrodes arranged at a distance from each other side-by-side so as to form a flow passage between them. Each one of the electrodes includes a sheet-shaped conductive member of electrically conductive material. The conductive member of at least one of the electrodes is at least partially enclosed by insulation of electrically non-conductive material. A layer of semiconducting material is arranged between the insulation and the associated conductive member on at least one side of the conductive member surface-to-surface with the conductive member, and/or the insulation is at least partially covered by a layer of semiconducting material arranged surface-to-surface with the insulation in order to smooth the electric fields on the outwardly facing surface of the insulation.Type: ApplicationFiled: May 15, 2007Publication date: July 9, 2009Applicant: Aibel ASInventors: Svein Tryti, Peder Hansson
