  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. Characterizing coil windings noise due to compressive fault currents : A study to determine if there is a characteristic noise from transformer windings due to fault currents

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

    Author : Simon Lundgren; [2022]
    Keywords : Transformer windings; short circuit forces; current pulses; microphone; Comsol Multiphysics; FFT; Transformator lindningar; strömpulser; mikrofon; kortslutingskrafter; Comsol Multiphysics; FFT;

    Abstract : Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. READ MORE
