1. Konditionsbedömning av en grupp transformatorer på Forsmark kärnkraftverk : Modellbaserad åldringsanalys av transformatorer
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This thesis used a model-based approach to assess the condition of a group of transformers at Forsmark nuclear plant. Since it’s problematic for practical and economic reasons to examine the paper insulation by inspection, this approach was chosen. LÄS MER
2. Livscykelanalys av en härvsats
Kandidat-uppsats, Högskolan i Gävle/MiljövetenskapSammanfattning : Livscykelanalys (LCA) används för att beräkna produktsystemets potentiella miljöpåverkan och identifiera hotspots i livscykeln. Resultatet kan användas för att tilllämpaåtgärder på produktsystemets hotspots för en minskad potentiell miljöpåverkan. LÄS MER
3. Allowing more solar power connected to the grid, using thermal and ageing models of distribution transformers.
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : Increasing amounts of solar power connected to the low-voltage network will adversely affect the performance of the network. The two impacts that will most often set the limit are overvoltage with the customers and overloading the distribution transformer. LÄS MER
4. Minimizing Transformer No-Load Losses at Hydropower Plants : A Study of Effects from Transformer Switch-Off During Stand-by Operation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknikSammanfattning : Hydropower is the most important power balancing resource in the Swedish electrical power system, regulating the power supply to match the load. Consequently, several hydropower plants have periods of stand-by operation where the power production is absent but where several devices within a plant are still active. LÄS MER
5. Influence of structural and materials properties on the flexural strength of laminated high-density cellulose fiberboards
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Laminated pressboard is a structural electrical insulation material used in power transformers. Typical applications are areas in the power transformers where high mechanical forces are present such as pressrings or winding tables and cleats which support the electrical cables connecting the transformer windings to tap-changes and bushings.
