    • 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 ...

    • Breakdown Mechanisms of Rod-Plane Air Gaps with a Dielectric Barrier Subject to Lightning Impulse Stress 

      Meyer, Hans Kristian Hygen; Mauseth, Frank; Pedersen, Per Atle; Ekeberg, Jonas (Journal article; Peer reviewed, 2018)
      The complexity of gas-insulated substations makes it difficult to predict withstand voltages. Modeling interaction between dielectric surfaces and electrical discharges is a key challenge. In this study, 60 mm rod-plane ...

    • Streamer and surface charge dynamics in non-uniform air gaps with a dielectric barrier 

      Meyer, Hans Kristian Hygen; Marskar, Robert; Blaszczyk, Andreas; Mauseth, Frank; Pedersen, Per Atle (Journal article; Peer reviewed, 2019)
      Streamer behaviour near dielectric surfaces is an important characteristic of air-solid electrical insulation systems. Accurate predictions are important for dielectric design, but dynamic aspects such as surface charging ...

    • 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 in short rod-plane air gaps – experiments and simulations 

      Meyer, Hans Kristian Hygen; Blaszczyk, Andreas; Schueller, Michael; Mauseth, Frank; Pedersen, Per Atle (Chapter, 2018)
      Surface charge on dielectric surfaces can alter the field conditions of insulation systems substantially. In this work, lightning impulse experiments are compared with a simulation model for surface charging in rod-barrier-plane ...

    • 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 ...
