Fast computation of the geoelectric field using the method of elementary current systems and planar Earth models [PDF]
Annales Geophysicae, 2004 The method of spherical elementary current systems provides an accurate modelling of the horizontal component of the geomagnetic variation field. The interpolated magnetic field is used as input to calculate the horizontal geoelectric field.

Installation of Induced Current Measurement Systems in Substations and Analysis of GIC Data during Geomagnetic Storms [PDF]
Journal of Astronomy and Space Sciences, 2015 Coronal Mass Ejections (CME), which originate from active regions of the Sun’s surface, e.g., sunspots, result in geomagnetic storms on Earth. The variation of the Earth’s geomagnetic field during such storms induces surface currents that could cause ...

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 ...

Analysis of Long‐Term GIC Measurements in Transformers in Austria
Space Weather, 2022 Geomagnetically induced currents (GICs), a result of solar wind interaction with the Earth's magnetic field and the resistive ground, are known to flow in power transmission grids, where they can lead to transformer damage and grid operation problems. In
