  1. 1. Strömmätsystem för 10 000 Ampere : Enligt Rogowskiprincipen

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Albin Klasson; [2023]
    Nyckelord :Rogowski; strömmätsystem; integrator; mätning; starkström;

    Sammanfattning : På RISE (Research Institutes of Sweden) finns en betydande kalibreringsverksamhet där avdelningen för högspänning önskar utöka sin strömmätningskapacitet för AC strömmar vid kraftfrekvens upp till 10 000 A.   Syftet är att med hjälp av Rogowskiprincipen bygga en mätrigg för kalibrering av strömtransformatorer i fält.

  3. 2. Design changes to simplify maintenance and condition assessment on a tap changer

    Master-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Arvid Fermér; Jakob Modling; [2023]
    Nyckelord :Power transformer; Chemical degradation; Electrical insulation; Tap changer; Insulation Electrical; Transformer insulation; Insulating oil; Insulation condition assessment; Transformer; Power grids; Power distribution; Oil filled transformer; Transformer oil;

    Sammanfattning : This master thesis investigates a redesign for a maintenance tube, used for both sampling and draining transformer oil from a tap changer compartment. With the current design, one can do one or the other of sampling and draining. LÄS MER

  4. 3. Design and investigation of a pulsating heat pipe for electronic cooling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sulafa Hammad; [2023]
    Nyckelord :Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

    Sammanfattning : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. LÄS MER

  5. 4. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Samuel Eriksson; [2023]
    Nyckelord :Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

    Sammanfattning : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. LÄS MER

  7. 5. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Joel Ekström; [2023]
    Nyckelord :Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Sammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER
