• Contact Resistance and Temperature Rise of Cable Connections in Cable Distribution Cabinets 

      Fjeld, Elin; Rondeel, Wilhelm G. J.; Sønsteby, Gunn Kristin; Bekken, Finn Werner; Eriksen, Thomas Ranvik (Conference lecture, 2020)
      Initiated by a number of fire accidents in the low voltage switchgear in cable distribution cabinets, investigations have been performed to identify the cause of these fires. The results indicate that the cable connection ...
    • Estimate the temperature rise of medium voltage metal enclosed switchgear by simplified heat transfer calculations 

      Fjeld, Elin; Rondeel, Wilhelm G. J.; Attar, Elham; Singh, Shailendra (Journal article; Peer reviewed, 2020)
      Electrical equipment will experience a rise in temperature during normal operation. During a development process, prototypes and laboratory tests will be required to make sure the temperature rises are within acceptable ...
    • High current arc erosion on copper electrodes in air 

      Øyvang, Thomas; Fjeld, Elin; Rondeel, Wilhelm; Hagen, Svein Thore (Journal article; Peer reviewed, 2011)
      An arc fault inside metal enclosed switchgear will cause the pressure to rise and vaporization of electrode material may contribute to the pressure rise. An experimental study of high current arc erosion on copper electrodes ...
    • Small scale arc fault testing of medium voltage metal enclosed switchgear 

      Fjeld, Elin; Hagen, Svein Thore (Journal article; Peer reviewed, 2016-03-16)
      Internal arc fault tests are important for ensuring the safety of medium-voltage metal-enclosed switchgears. Since these tests are conducted at full scale, the costs of the test objects as well as the high-power laboratory ...
    • Studentaktive Læringsformer for å Fremme Dyplæring i Høyspenningsteknikk 

      Fjeld, Elin; Tholin, Kristin Rydjord; Øhra, Mattias (Journal article, 2019)
      Denne studien baserer seg på perspektiver rundt dyplæring. Det søkes å vise hvordan mer tudentaktive læringsformer kan skape mere robuste læringspraksiser som igjen muliggjør dyplæring. Studien søker å vise at en slik ...
