   Nyckelord :Laser; Orbital; Debris; Removal;

   Sammanfattning : Overcrowding of the Low Earth Orbit (LEO) region is a growing problem. Decades of treating this part of space like a scrap yard has caused it to become a hazardous environment for operating satellites. LÄS MER

3. 2. GIC immune transformers - An evaluation of their GIC elimination and fault behaviour

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Kajsa Eriksson Rosenkvist; [2015]
   Nyckelord :GIC Geomagnetically Induced Currents Transformers Un-symmetrical faults; Technology and Engineering;

   Sammanfattning : Geomagnetically Induced Currents (GICs) arise from fluctuations in Earths magnetic field and can reach alarmingly high levels and cause malfunctions or blackouts in the power grids in which they occur. AF Klercker Alaküla and Lindahl invented a patented GIC immune transformer which eliminates the effects of GICs, though it is not known how this implementation will affect the transformers behavior during un-symmetrical faults.
