Investigation of Partial Discharges in AlN Substrates under Fast Transient Voltages
Semenov, Ivan; Gunheim, Ingrid Folkestad; Niayesh, Kaveh; Meyer, Hans Kristian Hygen; Lundgaard, Lars Esben (Peer reviewed; Journal article, 2022)The objective of this paper is to characterize partial discharge (PD) inception voltages and patterns at sinusoidal and square voltages in insulating ceramic substrates with generic manufacturing defects. PD tests were ... -
Partial Discharge Inception in Ceramic Substrates Embedded in Silicone Liquid, Silicone Gel, and Mineral Oil at Fast Voltage Rise and Sinusoidal Voltage
Semenov, Ivan; Aakre, Torstein Grav; Folkestad, Ingrid Gunheim; Smisethjell, Ingrid; Niayesh, Kaveh; Lundgaard, Lars Esben (Journal article; Peer reviewed, 2024)This paper summarizes experiments that were carried out on insulating ceramic substrates and a needle-plane arrangement with the purpose to characterize the inception of partial discharges (PD) in the insulation of ... -
Simulation and design of an electrodynamic Thomson coil actuator for fast mechanical switches
Hansen, Håkon Risbøl (Master thesis, 2022)En Thomson spole aktuator er en ultra-rask elektromagnetisk driv mekanisme. Drivmekanismen skal brukes til å drive den mekaniske bryteren i en hybrid likestrøms- (HVDC) effektbryter. Ved å utbedre designet av Thomson spolen ...
