Breakdown at Multiple Protrusions and Surface Roughness in SF6 and CO2 - A Study of the Enlargement Law
Feet, Odd Christian (Master thesis, 2018)Gas insulated components are important in the modern transmission system. The most common gas used in high pressure insulation is Sulphur Hexafluoride (SF6). SF6 has beenclassified as a greenhouse gas and a potential ... -
Breakdown at Multiple Protrusions in SF6 and CO2
Feet, Odd Christian; Seeger, Martin; Over, Daniel; Niayesh, Kaveh; Mauseth, Frank (Peer reviewed; Journal article, 2020)The electric breakdown at single and multiple protrusions in SF6 and CO2 is investigated at 0.4 and 0.6 MPa, respectively. Additionally, the breakdown fields at rough surfaces of two different areas were determined. From ... -
Influence of Surface Roughness on Breakdown in Air Gaps at Atmospheric Pressure under Lightning Impulse
Feet, Odd Christian; Mauseth, Frank; Niayesh, Kaveh (Chapter, 2018)In high voltage equipment, gases are often used as insulation material. Several parameters can influence the dielectric withstand voltage of gaseous insulation systems, such as the degree of inhomogeneity, gas pressure and ...
