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

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Arvid Fermér; Jakob Modling; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. A micro-CT investigation of density changes in pressboard due to compression

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Johan Stjärnesund; [2018]
    Keywords : Micro computed tomography; μCT; pressboard; density; densification;

    Abstract : Pressboard, a high-density cellulose-based product, is used both as load bearing structures and dielectric insulation in oil-filled power transformers. During transformer operation, mechanical forces and vibrations are applied on the material. READ MORE

  4. 3. Functional performance criteria for comparison of less flammable transformer oils with respect to fire and explosion risk

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Denis Hellebuyck; [2013]
    Keywords : Flammability; transformer oils; fire and explosion risk; cone calorimeter test; Technology and Engineering;

    Abstract : Power grids worldwide are expanding not only driven by ambitious clean energy, but also because of the rising need for reliable energy. Key components of these power grids are transformers. Transformers are traditionally filled with mineral oil, to serve as a coolant and dielectric insulator. READ MORE

  5. 4. Analysis of Partial Discharge in OIP Bushing Models

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Zeeshan Ahmed; [2011]
    Keywords : ;

    Abstract : A high voltage bushing is a very important accessory of power transformers. Bushings are used to insulate high voltage conductors where they feed through steel tank of a power transformer. There are different sources of electric stress that may result in degradation of bushing. READ MORE
