  • Power transmission arrangement and method for operating a power transmission arrangement
    Patent number: 10097002
    Abstract: Embodiments are generally based on employing a power transmission line in a HVDC link to provide auxiliary power to one of the ends of the HVDC link for facilitating a black start thereof when the HVDC link is de-energized, i.e. when at least one of the HVDC converter stations is de-energized and there is no transmission of power between inverter and rectifier HVDC converter stations on each side of the HVDC link. A relatively small amount of power can be conveyed towards one of the HVDC converter stations via the power transmission line so as to provide power to any auxiliary system(s) of the converter station, for example prior to a black start of the converter station being carried out.
    Type: Grant
    Filed: June 30, 2015
    Date of Patent: October 9, 2018
    Assignee: ABB SCHWEIZ AG

  • Device for measuring the direct component of alternating current
    Patent number: 9279836
    Abstract: The invention relates to a device for measuring the direct component of alternating current, applicable in current measuring systems where a low direct component of alternating current and a high amplitude of the alternating component of alternating current occur. The device for measuring the direct component of alternating current comprises a current-carrying wire (1) around which there is located a magnetic core (2) provided with a gap (3) in which a magnetic field sensor (4) with insulated terminals (5) is located and it comprises a shorted compensating winding (6) or (9) which is made in the form of a single turn coil placed on the core (2).
