Streamer and surface charge dynamics in non-uniform air gaps with a dielectric barrier
Meyer, Hans Kristian Hygen; Mauseth, Frank; Maskar, Robert; Pedersen, Per Atle; Balszczyk, Andreas (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 (Conference on Electrical Insulation and Dielectric Phenomena. Annual Report;2016, Chapter; Peer reviewed, 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 ... -
