Charge accumulation on slightly conductive barrier systems and its effect on breakdown voltage in an air insulated rod plane arrangement
Schueller, M.; Blaszczyk, Andreas; Mauseth, Frank; Meyer, Hans Kristian Hygen; Stieger, N.; Smajic, J. (Chapter, 2020)The barrier effect has been known since the 1930's. It is of great importance in the field of high voltage engineering as the breakdown voltage of an electrode arrangement can be increased significantly when dielectric ... -
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 ... -
Surface charging formulations for engineering applications: Validation by experiments and transient models
Blaszczyk, Andreas; Christen, Thomas; Meyer, Hans Kristian Hygen; Schueller, Michael (Chapter, 2020)Electrostatic BEM (Boundary Element Method) formulations are presented for the calculation of dielectric surface charging, including saturation and restrike phenomena. The simulation results turn out to be in agreement ... -
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 ...
