    Sammanfattning : This thesis explores the losses occurring in a specific region located in the southern part of Eskilstuna, where ESEM serves as the network owner. The study places particular emphasis on power factor and load factor as key factors. Its objective is to analyze and comprehend the extent of losses in the network and their implications. LÄS MER

  2. 2. Evaluation of thermal expansion in busbars used for battery electric vehicles

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FREDRIK LARSSON; [2021]
    Nyckelord :Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Sammanfattning : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. LÄS MER

  3. 3. Study of Analytical Models for Harmonic Losses Calculations in Traction Induction Motors

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Anaïs Maroteaux; [2016]
    Nyckelord :Analytical model; Bertotti; curve fitting; FEM 2D; harmonic losses; induction mo-tor; iron losses; Joule losses; skin and proximity effects.; Analytisk modell; Bertotti; kurvanpassning; FEM 2D; harmoniska förluster; asynkro-nmotor; järnförluster; Joule förluster; skineffekt och proximity effekt.;

    Sammanfattning : This Master Thesis deals with the study of analytical and finite-element (FE) models for calculation of losses in traction induction motors. Motors are fed through inverters for this type of application. Therefore, both fundamental and harmonic losses are considered. The study is done with one particular motor and one initial analytical model. LÄS MER
