Pre-Breakdown Phenomena in Technical Air with and without C5-Fluoroketone for a Rod-Plane Gap
Skirbekk, Fanny; Mauseth, Frank; Meyer, Hans Kristian Hygen (Journal article; Peer reviewed, 2022)alternatives to the potent greenhouse gas SF6 in medium voltage (MV) gas insulated switchgear. MV products using this gas mixture are already commercially available, but there is still a lack of knowledge about this gas ... -
Streamer inception in technical air with and without C5-fluoroketone for a rod-plane gap
Skirbekk, Fanny; Marskar, Robert; Meyer, Hans Kristian Hygen; Mauseth, Frank (Chapter, 2024)In this study, the inception probability of negative streamers in technical air with 7.5 %vol C5-fluoroketone (C5-FK+air) at 1.0 bar absolute pressure is studied. Similar tests were done for both polarities in technical ... -
Streamer Inception Probability in Air - How the Polarity Dependence is Affected by Changes in the Shape of the Applied Voltage Impulse
Skirbekk, Fanny; Andresen, Martin Tiller; Mauseth, Frank (Chapter, 2024)In this research, the influence of the rise time of the applied voltage pulse on the polarity dependence for streamer inception probability in air is studied. This was done for a needle-plane electrode configuration at ... -
Streamer inception probability in air at atmospheric pressure - An experimental and theoretical analysis
Skirbekk, Fanny; Meyer, Hans Kristian Hygen; Mauseth, Frank; Marskar, Robert (Journal article; Peer reviewed, 2024)We consider a self-consistent and probabilistic formulation of the classical Raether-Meek streamer inception model, and compare it with dedicated experiments. Our approach is based on the statistical evaluation of a first ... -
Transformer insulation stressed by power converters
Skirbekk, Fanny (Master thesis, 2021)For å kunne ta i bruk flere fornybare energikilder i kraftsystemet, med så lite effekttap som mulig, blir stadig mer kraftelektronikk tatt i bruk i kraftsystemet. Kraftelektronikkomformere brukes primært til å skru av og ...
