2015 7th International Conference on Recent Advances in Space Technologies (RAST), 2015
We present our preliminary results for the ground level electric and magnetic field variations in Turkey using Bozcaada station (GEO: 39.500N, 26.020E, MAG: 40.370N, 26.030E) magnetotelluric measurements. We find that our quiet day observations agree well with the expected magnetic field variations for the magnetic field components at mid-latitudes ...

Effects of Geomagnetically Induced Currents-GIC on Electric Power Technology in Brazil
11th International Congress of the Brazilian Geophysical Society & EXPOGEF 2009, Salvador, Bahia, Brazil, 24-28 August 2009, 2009Geoelectric fields induced in the Earth during geomagnetic storms drive electric currents through the windings of power transformers and the transmission lines carrying electric power. These currents, known as GIC (Geomagnetically Induced Currents), flow in the entire electric power systems and cause deleterious effects.

We present the study of sequence of geomagnetic storm (GMS) and its relation with the two solar flare events on 20th April 2020 and 29th May 2020. The parameter such as solar wind, interplanetary magnetic field (IMF) and Kp index play an important roles and affect the GIC level and climate change.

Simulation analysis of geomagnetically-induced currents (GIC) effects on shell-form transformers
2013 IEEE Power & Energy Society General Meeting, 2013Transformer DC excitation due to geomagnetically-induced currents was studied by 3D analysis based on an in-application 280 MVA 500kV/230kV single phase auto transformer design. As a result of previous studies, the transformer design studied here incorporated non-magnetic stainless steel to limit local heating.

The Effect of Geomagnetically Induced Current(GIC) on the Domestic Power Grids
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2012There have been a lot of reports about the effects of geomagnetically induced current(GIC) on the power grids. However there has been little domestic efforts made in this relatively urgent area which include academic research or risk assessments on GIC.

Geomagnetically induced currents (GIC) are very harmful to the power system and caused by the changes of geomagnetic field. The changing magnetic fields originate from the interplanetary space. Therefore, recognizing the relationship between GIC and interplanetary disturbances is significant for the prediction of GIC. In this paper, we collected 35 GIC
