16. The role of magnetic perturbations in runaway electron and sawtooth dynamics
Sammanfattning : Nuclear fusion in tokamaks is a possible future energy production mechanism. Some of the still unsolved problems are connected to the effect of magnetic perturbations on the radial plasma transport. Two such problems are addressed in this thesis. LÄS MER
17. Losses in high-pemperature superconductiong tapes in longitudinally applied magnetic fields
Sammanfattning : .... LÄS MER
18. Effect of Dielectric and Magnetic Material Characteristics on Frequency Response of Power Transformers
Sammanfattning : Frequency response analysis (FRA) technique has become increasingly popular for the assessment of mechanicalintegrity in power transformers. This method is based on the fact that the shape of the frequency response at higher frequencies is uniquely determined by the geometrical construction of the transformer. LÄS MER
19. Development of loss models for a high-temperature superconducting tape
Sammanfattning : In the recent years significant progresses in thedevelopment of high-temperature superconductors have been made.It is realistic to believe that power applications, based onthese conductors, in a few years will become available. LÄS MER
20. AC losses in HTS as a function of magnetic fields with arbitrary directions
Sammanfattning : Although a superconductor has zero resistivity when carrying a direct current, losses do occur when it is exposed to an alternating magnetic field and/or is carrying an alternating current. The magnitude of these so-called AC losses depends on the operating temperature, the amplitude and the direction of the magnetic field, the transport current, and the frequency. LÄS MER
