  1. 1. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints

    University essay from Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknik

    Author : Sivert Knutsen; [2023]
    Keywords : wood; engineering; construction; massive timber; tube joints; Progressive collapse;

    Abstract : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. READ MORE

  3. 2. Single- or Three-Phase Supply to Homes : Advantages and Disadvantages compared between Single-phase and Three-phase domestic electricity

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

    Author : Alexander Grönblad; [2022]
    Keywords : Elecricity Tariff; Single-phase Supply; Three-phase Supply; Load Curve; Homes; Eltariff; Enfasmatning; Trefasmatning; Lastprofil; Bostäder;

    Abstract : A three-phase power supply is a de facto standard when selecting a power supply to homes in Sweden, regardless of whether it is flat with low energy consumption or a house with electric heating. This project aims to determine the advantages and disadvantages of using a three-phase supply compared to a single-phase supply to homes. READ MORE

  4. 3. Tests of Series Arcing and Arc Fault Detection Devices in Low Voltage Systems

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

    Author : Ghazal Al Qabbani; [2021]
    Keywords : ;

    Abstract : Unwanted electrical arcs are a concern in fire and electrical equipment safety. Arcs in electrical systems can be categorized into two main groups, traditionally called: Series and parallel arc faults, or more recently called low current and high current arc faults. READ MORE

  5. 4. Simulations of Pre-arcing Times in Diazed Fuses by an Electrothermal Dynamic Model

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

    Author : Amadeus Andersson Jonsson; [2020]
    Keywords : Diazed fuses; Pre-arcing time; The finite differ-ence method; thermoelectrical fuse model;

    Abstract : The determination of the pre-arcing time of a fuse given a specific current is crucial during the selection process if the fuse is to be effective for the given application. Often the data supplied by the manufacturer is enough to determine this time, however this is not always the case. READ MORE

  6. 5. Investigation of electromagnetic compatibility (EMC) of low-voltage (<60V) DC electric motors in construction machinery application

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : David Luong; Ibrahim Salloum; [2019]
    Keywords : EMC; brushed dc motor; arcing; inrush currents; X2Y capacitor; NTC thermistor; common mode ferrites; differential mode ferrites; grounding; cable placement; motor design parameters;

    Abstract : The brushed DC motor is a source of electromagnetic emission that may cause interference. The main issues with brushed DC motor are arcing, which occurs between the brushes and commutator, and inrush current. It is possible to decrease the electromagnetic emissions by addressing the source (brushed dc motor) and the installation. READ MORE
