Cerman: Software for simulating streamer propagation in dielectric liquids based on the Townsend–Meek criterion
Madshaven, Inge; Hestad, Øystein Leif Gurandsrud; Åstrand, Per-Olof (Peer reviewed; Journal article, 2021)We present a software to simulate the propagation of positive streamers in dielectric liquids. Such liquids are commonly used for electric insulation of high-power equipment. We simulate electrical breakdown in a needle–plane ... -
Dielectric Performance of Transformer Liquids–Summary of a CIGRE Study
Lundgaard, Lars Esben; Liu, Qiang; Lesaint, Olivier; Madshaven, Inge (Peer reviewed; Journal article, 2023)This article reviews the functional requirements, dielectric performance, and test standards of insulating liquids from a transformer design perspective. -
Modeling the transition to fast mode streamers in dielectric liquids
Madshaven, Inge; Åstrand, Per-Olof; Hestad, Øystein Leif Gurandsrud; Unge, Mikael; Hjortstam, O. (Proceedings of IEEE International Conference on Dielectric Liquids;2017, Chapter; Peer reviewed, 2017)A simplified model for photoionization, modeling fast streamer propagation, is combined with an existing model for slow streamers, based on electron avalanches. Transitions from fast mode to slow mode, and from slow mode ... -
Photoionization model for streamer propagation mode change in simulation model for streamers in dielectric liquids
Madshaven, Inge; Hestad, Øystein Leif Gurandsrud; Unge, Mikael; Hjortstam, Olof; Åstrand, Per-Olof (Journal article; Peer reviewed, 2019)Radiation is important for the propagation of streamers in dielectric liquids. Photoionization is a possibility, but the effect is difficult to differentiate from other contributions. In this work, we model radiation from ... -
