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

Geomagnetically induced currents (GIC) are a ground end manifestation of space weather processes. During the large geomagnetic storms the GIC end up flowing between the ground points of the power transformers and the electric power transmission lines connecting the transformers.

Modeling & Mitigation of Geomagnetically Induced Currents (GICs) for Single-Phase Power Transformer
2018 International Conference on Computer, Control, Electrical, and Electronics Engineering (ICCCEEE), 2018This paper describes the effect of Geomagnetically Induced Currents (GICs) in single phase-transformer and how to mitigation the phenomena using capacitor at the ground for the transformer, Geomagnetically Induced Currents (GICs) arise from fluctuations in Earth’s magnetic field and can reach alarmingly high levels and cause malfunctions or blackouts ...

Abstract Geomagnetically induced currents (GIC) in technological systems are ground effects of space weather. In electric power transmission networks, GIC may produce problems by saturating transformers. Thus, GIC flowing into and from the Earth through transformers are more important in practice than GIC in transmission lines. In this paper, we show
