    • A novel bench size model coalescer: Dehydration efficiency of AC fields on water-in-crude-oil emulsions 

      Lesaint, Cedric Michel; Berg, Gunnar; Lundgaard, Lars Esben; Ese, Marit-Helen Glomm (Journal article; Peer reviewed, 2016)
      We describe herein the design of a small AC electrostatic model coalescer for investigating coalescence efficiency of water in oil emulsions. The function of the model coalescer is tested on emulsions with different water ...

    • Comparison between synthetic ester and mineral oil impregnated transformer paper aging markers 

      Liland, Knut Brede; Linhjell, Dag; Lesaint, Cedric Michel; Ese, Marit-Helen Glomm; Lundgaard, Lars Esben; Mavrommatis, Pascal; Stjepanovic, Nenad Miroljub (Proceedings of IEEE International Conference on Dielectric Liquids;, Chapter; Peer reviewed, 2017)
      For transformers in service, aging markers from cellulose in oil such as furans, water, methanol and acids are measured for diagnostic purposes. The content of these indicators, measured in oil, may therefore vary with ...

    • Compatibility of liquid and solid insulation materials for high voltage subsea connectors 

      Lesaint, Cedric Michel; Hølto, Jorunn; Sæternes, Hans Helmer; Ese, Marit-Helen Glomm (Journal article; Peer reviewed, 2019)
      The main objective of this study is to identify reliable insulation materials and systems for novel AC and DC subsea power connectors for oil and gas exploitation. A combined solid-liquid insulation system might be radically ...

    • Electrical aging of fluoropolymer cable insulation materials induced by partial discharge 

      Kantar, Emre; Klusmeier, Katharina Kuhlefelt; Ve, Torbjørn Andersen; Ese, Marit-Helen Glomm; Hvidsten, Sverre (Peer reviewed; Journal article, 2024)
      This study investigates AC electrical aging induced by partial discharge (PD) in fluoropolymer cable insulation materials, namely fluorinated ethylene propylene (FEP) and perfluoroalkoxy (PFA), with the cross-linked ...

    • Electrical Treeing in Fluoropolymer Cable Insulation 

      Ve, Torbjørn Andersen; Syvertsen, Hilde Marie Tollefsrud; Thomsen, Nina Marie; Ese, Marit-Helen Glomm; Kantar, Emre; Hvidsten, Sverre (Peer reviewed; Journal article, 2024)
      This paper examines the electrical treeing phenomenon in fluoropolymers under AC voltage. A specialised test setup was designed to evaluate two distinct fluoropolymers, fluorinated ethylene propylene (FEP) and perfluoroalkoxy ...

    • Electrocoalescence III : staus and summary report from activities 

      Lundgaard, Lars Esben; Munkejord, Svend Tollak; Reboud, Jean-Luc; Lesaint, Cedric Michel; Ervik, Åsmund; Ese, Marit-Helen Glomm (SINTEF Energi. Rapport;, Research report, 2016)

    • Epoxy-Based Nanocomposites for High-Voltage Insulation: A Review 

      Adnan, Mohammed Mostafa; Tveten, Erlend Grytli; Glaum, Julia; Ese, Marit-Helen Glomm; Hvidsten, Sverre; Glomm, Wilhelm; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2018)
      Epoxy nanocomposites, with inorganic oxide nanoparticles as filler, can exhibit novel property combinations, such as enhanced mechanical strength, higher thermal conductivity, increased dielectric breakdown strength, and ...

    • The Structure, Morphology, and Complex Permittivity of Epoxy Nanodielectrics with in Situ Synthesized Surface-Functionalized SiO2 

      Adnan, Mohammed Mostafa; Nylund, Inger-Emma; Jaworski, Aleksander; Hvidsten, Sverre; Ese, Marit-Helen Glomm; Glaum, Julia; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2021)

    • Theoretical and Experimental Determination of Thermomechanical Properties of Epoxy-SiO<inf>2</inf> Nanocomposites 

      Adnan, Mohammed Mostafa; Kroyan, Arpenik; Srivastava, Chaman; Grammatikos, Sotirios; Glaum, Julia; Ese, Marit-Helen Glomm; Schnell, Sondre Kvalvåg; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2023)
      Improvements in the thermomechanicalproperties of epoxy upon inclusion of well-dispersed SiO2nanoparticles have been demonstrated both experimentally and through molecular dynamics simulations.The SiO2was represented by ...
