    • Air Flow Measurements During Medium-Voltage Load Current Interruptions 

      Aanensen, Nina Sasaki; Runde, Magne (Journal article; Peer reviewed, 2015)
      Air has been considered a good alternative to SF6 as arc quenching medium for load break switchgear at medium voltage ratings. In this work, the air flow characteristics and influence from the electric arc have been studied ...

    • 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 ...

    • 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 ...
