  3. 2. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emil Bergvall; [2023]
    Nyckelord :DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

    Sammanfattning : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. LÄS MER

  4. 3. Battery field data-oriented investigation of cell capacity spread and its impacts

    Master-uppsats,

    Författare :Muhammad Bilal; [2022]
    Nyckelord :Cell Capacity; Electric Vehicles; Algorithm; Current Profile; Voltage;

    Sammanfattning : In this research thesis, a new data-centric approach is used to determine the individual cell capacities in Li-ion batteries used in electric vehicles (EVs). This approach could also be extended to batteries for static energy storage applications. LÄS MER

  5. 4. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Edvin Nilsagård; Rebecka Knutsson; [2022]
    Nyckelord :ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Sammanfattning : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. LÄS MER

  7. 5. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

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

    Författare :Martin Fajerberg; Mattias Nylander; [2022]
    Nyckelord :Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Sammanfattning : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. LÄS MER
