  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sara Lenman; Sofia Blaad; [2023]
    Keywords : Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Abstract : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. READ MORE

  3. 2. Stray capacitance study for HVDC Classic : The use of PSCAD and Mathcad to calculate the equivalent stray capacitance

    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

  4. 3. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit

    University essay from Stockholms universitet/Fysikum

    Author : Guillermo Lopez Basurco; [2022]
    Keywords : Geant4; Monte Carlo simulations; XFEL undulators; gamma radiation flux;

    Abstract : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. READ MORE

  5. 4. Shielding of Transformer Stray Fields in Trains

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lárusdóttir Lára Ólafia; [2022]
    Keywords : ;

    Abstract : Generally, a transformer will produce stray magnetic fields. Aboard trains, the transformer’s stray fields can pose problems to other components inside or outside the train. Further, regulations require the magnetic field to be below certain levels in the passenger area. READ MORE

  6. 5. Design of current transformer energy harvesting power supply

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oscar Bäckman; [2021]
    Keywords : Energy harvesting; Current transformer;

    Abstract : This thesis explores the possible method to harvest energy from ambient sources around power transformers. These include magnetic induction and vibration. The objective is to create an energy harvester device that can output enough energy to power multiple sensors, wireless connectivity and an MCU. READ MORE
