Geomagnetic disturbances cause perturbations in the Earth's magnetic field which, by the
principle of electromagnetic induction, in turn cause electric currents to flow in the Earth …

Geomagnetically induced current (GIC) has been a significant concern for the electrical
power grid in high latitudes for decades. Its origin starts in the Sun; during extreme space …

Several periods of geomagnetically induced currents (GICs) were detected in the Halfway
Bush substation in Dunedin, South Island, New Zealand, as a result of intense geomagnetic …

Abstract Space Weather is the study of the dynamics of the coupled Solar‐Terrestrial
environment, as these dynamics impact technological systems and human activity. This …

Magnetotelluric (MT) impedances from 62 sites in southern South Island of Aotearoa New
Zealand have been used to model geomagnetically induced currents (GIC) in four …

During space weather events, geomagnetically induced currents (GICs) can be induced in
high‐voltage transmission networks, damaging individual transformers within substations. A …

Geomagnetically induced currents (GICs) during a space weather event have previously
caused transformer damage in New Zealand. During the 2015 St. Patrick's Day Storm …

Abstract Space weather poses a hazard to grounded electrical infrastructure such as high
voltage (HV) transformers, through the induction of geomagnetically induced currents …

The forecasting of local GIC effects has largely relied on the forecasting of dB/dt as a proxy
and, to date, little attention has been paid to directly forecasting the geoelectric field or GICs …

In recent years, several magnetic storms have disrupted the normal operation of power grids
in the mid-low latitudes. Data obtained from the monitoring of geomagnetically induced …
