    University essay from Uppsala universitet/Elektricitetslära

    Author : Saga Dalersand; Fredrik Gjöthlén; [2023]
    Keywords : ;

    Abstract : The reactors placed in the thyristor valve designed by Hitachi Energy have reactor losses which are dependent on the stray capacitance. To find out the stray capacitance, and further get to know the reactor losses, a PSCAD simulation is performed. READ MORE

  3. 2. Measurement system for pre-discharge currents in HVDC tests

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Saga Dalersand; Edvin Bäckstadi; Fredrik Gjöthlén; [2021]
    Keywords : ;

    Abstract : To measure the current impulses before a discharge process in an insulation material is completed a proposed system has been built theoretically. The blocks in the system have been studied by going through relevant sources and meetings with the supervisor of the project and new ideas have been considered. READ MORE
