Geomagnetic Pulsations Driving Geomagnetically Induced Currents
Space Weather, 2021 Geomagnetically induced currents (GICs) are driven by the geoelectric field induced by fluctuations of Earth's magnetic field. Drivers of intense GICs are often associated with large impulsive events such as coronal mass ejections.

The Impact of Geomagnetically Produced Negative-Sequence Harmonics on Power Transformers
IEEE Access, 2021 Geomagnetically induced currents (GICs), although small in magnitude, can inflict detrimental effects on power systems. GICs damage transformers, generate unusual harmonics, trip reactive power support equipment, cause protective relays to malfunction ...
