    • Breakdown in short rod-plane air gaps under positive lightning impulse stress 

      Hygen Meyer, Hans Kristian; Mauseth, Frank; Pedersen, Per Atle; Martine, Husøy (Journal article; Peer reviewed, 2017)
      Prediction of withstand voltages in air-insulated systems are made on the basis of empirical models that are not sufficiently accurate for complex geometries. Bet-ter understanding of the spatio temporal ...

    • Streamer Propagation in Rod-Plane Air Gaps with a Dielectric Barrier 

      Hygen Meyer, Hans Kristian; Mauseth, Frank; Pedersen, Per Atle; Ekeberg, Jonas (Chapter, 2016)
      High-voltage design optimization requires a fun- damental understanding of electrical breakdown mechanisms under different stress situations. The impulse withstand voltage is normally used as dimensioning criterion for ...

    • Surface charging of dielectric barriers under positive lightning impulse stress 

      Hygen Meyer, Hans Kristian; Mauseth, Frank; Pedersen, Per Atle; Husøy, Martine (Chapter, 2017)
      The complex geometry of gas-insulated substations makes it difficult to predict withstand voltages. A key challenge is the characterization of the interaction between electrical discharges and dielectric surfaces. A 60 mm ...
