Currents in AC stressed liquid insulated needle plane gap
(Chapter; Peer reviewed, 2014)Currents and space charge phenomena in 8 different dielectric liquids have been investigated for an ac stressed needle plane gap. Applied frequencies ranged from 0.1 Hz to 100 Hz. A high resolution analogue-digital converter ... -
Absorption of water in silicon gel
(Chapter; Peer reviewed, 2014)Water is an important enemy of an electric insulation system. Water vapour can be absorbed by electrical insulation materials (liquids or solid) and migrate in between the materials to achieve the same relative humidity ... -
Liquid insulation of IGBT modules: Long term chemical compatibility and high voltage endurance testing
(Chapter; Peer reviewed, 2016)To facilitate operation of power electronics for subsea operation at ambient pressure components have to be submerged in a liquid. Equipment and schemes for testing of long term properties have been developed. Several ... -
Estimation of environmental impacts from renewable energy technologies for application in a multi-criteria decision model
(Peer reviewed; Journal article, 2023)The share of electric vehicles and plug-in hybrid electric vehicles in the pabenger car stock has been steadily increasing over the last few years. This results in an increasing need for energy hubs and charging facilities ... -
How to accurately fast-track sorbent selection for post-combustion CO2 capture? A comparative assessment of data-driven and simplified physical models for screening sorbents
(Peer reviewed; Journal article, 2023)The recent discovery of a multitude of hypothetical materials for CO2 capture applications necessitated the development of reliable computational models to aid the quest for better-performing sorbents. Given the computational ... -
Hydrothermal Gasification of Biogas Digestate: a Parametric Study Using a Matlab-based Code
(Peer reviewed; Journal article, 2023)In this work, effect of process parameters on hydrothermal gasification (HTG) of biogas digestate are thermodynamically investigated using a Matlab-based code, which is capable of modelling the effects of the feedstock’s ... -
