Geomagnetic Disturbances in Electric Power Systems and Power Transformer Protection Against Geomagnetic Induced Currents Open
Geomagnetic storms (GMS) pose a real threat to electric power systems not only in the Russian Arctic zone but also in mid-latitude territories due to the long-term natural trend of the magnetic pole shifting from the territory of Canada to…
