Calculation of GIC in the North Island of New Zealand Using MT Data and Thin‐Sheet Modeling
Geomagnetically induced currents (GICs) in the North Island New Zealand power transmission network during two large magnetic storms are calculated from both magnetotelluric (MT) data and a thin‐sheet conductance model of New Zealand previously used to ...

Characterisation of grain orientated electrical steels under high DC biased conditions [PDF]
Power transformers are designed to operate under pure AC excitation, however they may be subjected to superimposed DC voltages and consequential offset currents, for example from geomagnetically induced currents, GICs, arising from solar activity.

Abstract Auroral substorms are a key manifestation of solar‐terrestrial interactions and the release of energy within the Earth's magnetosphere. The expansion phase, which is characterized by rapid changes in auroral morphology and intensity, poses significant space weather risks to satellite operations and communication systems.

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Analysis of Long‐Term GIC Measurements in Transformers in Austria
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

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Improvement in the modelling of geomagnetically induced currents in Southern Africa [PDF]
One of the consequences of the geomagnetic storms resulting from adverse space weather is the induction of geomagnetically induced currents (GICs) in power lines. The GICs that flow in a power transmission network are driven by the induced electric field
