    Nyckelord :Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

    Sammanfattning : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. LÄS MER

  3. 2. Power Transformer Monitoring and Diagnosis using Transformer Explorer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Svante Karlsson; [2016]
    Nyckelord :;

    Sammanfattning : Power transformers are one of the most expensive and vital components in the power system. A sudden failure could be a very costly process for both the transformer owner and the society. LÄS MER

  4. 3. Manufacturing Effects on Iron Losses in Electrical Machines

    Sammanfattning : In this master thesis, the magnetic properties of SiFe laminations after cutting and welding are studied. The permeability and the iron loss density are investigated since they are critical characteristics for the performance of electrical machines. LÄS MER

  5. 4. Further development of a pulse magentizer

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jon Axelsson; Per Söderberg; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A machine for magnetizing permanent magnets is under development at LTH. The idea of the machine is to affect only small pieces of a magnet at the time to obtain magnets with an arbitrary flux density, of course with respect to the magnetic material. The final machine is supposed to work in a closed loop fashion. LÄS MER
