    • Arc extinction with nitrogen at 1-40 bar in a puffer-like contact configuration 

      Støa-Aanensen, Nina Sasaki; Espedal, Camilla; Rokseth, Oddgeir; Jonsson, Erik; Runde, Magne (Peer reviewed; Journal article, 2021)
      To develop cost-efficient subsea switchgear for large sea depths, the extinction of arcs under high filling pressures must be understood. In this work, arc-extinction experiments have been performed with a puffer-like ...

    • Arc Voltage Distribution Measurement in Tube Constricted Ultrahigh-Pressure Nitrogen Arc 

      Abid, Fahim; Niayesh, Kaveh; Støa-Aanensen, Nina Sasaki (Lecture Notes in Electrical Engineering;599, Chapter; Peer reviewed, 2020)
      This work contributes to the fundamental understanding of axial voltage distribution of the arc burning inside polytetrafluoroethylene (PTFE) tube at very high filling pressures of nitrogen. The arc peak current of 85 A ...

    • Comparison of Different Air Flow Concepts for a Medium Voltage Load Break Switch 

      Støa-Aanensen, Nina Sasaki; Jonsson, Erik; Runde, Magne (Journal article; Peer reviewed, 2019)
      The research and development work towards a compact SF6-free load break switch for the medium voltage range has led to several design proposals. The interruption capability of three different nozzle and gas flow concepts ...

    • Contact and nozzle wear from 100 interruptions for a puffer-type air load break switch 

      Støa-Aanensen, Nina Sasaki; Jonsson, Erik; Runde, Magne (Journal article; Peer reviewed, 2017)
      One type test requirement for medium voltage load break switches is to interrupt 100 consecutive "mainly active loads". A puffer-type switch with axial-blown arc has been tested according to the 630 A/24 kV ratings. The ...

    • Eco-efficient puffer-type load break switch for medium voltage applications 

      Attar, Elham; Saxegaard, Magne; Hyrenbach, Maik; Homayonifar, Pouria; Bratsberg, Tor; Grauhaug, Ole; Støa-Aanensen, Nina Sasaki; Jonsson, Erik (Journal article; Peer reviewed, 2019)

    • Effect of Filling Pressure on Post-Arc Gap Recovery of N2 

      Abid, Fahim; Niayesh, Kaveh; Viken, Egil; Støa-Aanensen, Nina Sasaki; Jonsson, Erik; Meyer, Hans Kristian Hygen (Peer reviewed; Journal article, 2020)
      Experimental investigation of the effect of filling pressure on the post-arc dielectric recovery characteristics of nitrogen is reported in this paper. A half-cycle arc current duration of 540 μs followed by a 10 kV pulse ...

    • Erfaringer og resultater fra case-studier : IPN ElMar 

      Strand, Henrik; Støa-Aanensen, Nina Sasaki; Mehammer, Eirill Bachmann; Berg, Thor André; Hagen, Jens Eirik; Gjørven, André; Hansen, Svetlana; Meisler, Terje Robert; Stormo, Kjersti; Hunstad, Rakel; Houge, Jon August (SINTEF Rapport;, Research report, 2023)
      Denne rapporten har med utgangspunkt i ElMar-prosjektets fem casestudier samlet erfaringer fra planlegging, etablering, drift og bruk av landstrømsanlegg. Erfaringene kommer fra flere aktører (havner, nettselskap, ...

    • Short-Circuit making of medium voltage load break switches using a grid Connected test circuit 

      Jabs, Philipp; Niayesh, Kaveh; Støa-Aanensen, Nina Sasaki (Chapter; Peer reviewed, 2018)
      Short-Circuit making of medium voltage load break switches using a grid Connected test circuit

    • Thermal interruption performance of ultrahigh-pressure free-burning nitrogen arc 

      Abid, Fahim; Niayesh, Kaveh; Thimmappa, Shashidhara Basavapura; Espedal, Camilla; Støa-Aanensen, Nina Sasaki (Lecture Notes in Electrical Engineering;599, Chapter; Peer reviewed, 2020)
      In this paper, an experimental investigation of the thermal interruption performance of free-burning nitrogen arcs at 1 bar, 20 bar, and 40 bar filling pressures is reported. This work contributes to the fundamental ...

    • Ultrahigh-Pressure Nitrogen Arcs Burning Inside Cylindrical Tubes 

      Abid, Fahim; Niayesh, Kaveh; Støa-Aanensen, Nina Sasaki (Journal article; Peer reviewed, 2018)
      When the pressure and temperature of a fluid exceed a critical point, the fluid enters into the supercritical (SC) region. In this region, the physical properties are believed to be in favor of a good current interruption ...
