Geomagnetic induced current detection and monitoring
7th International Conference on Developments in Power Systems Protection (DPSP 2001), 2001In order to limit the potential for damage which a geomagnetic storm could cause, it is important to understand what level of current is being induced in a power system, when this is occurring and for how long. In conjunction with magnetic field data produced by the British Geological Survey, ScottishPower has developed a monitoring system which ...

Why utilities respect geomagnetically induced currents
Journal of Atmospheric and Solar-Terrestrial Physics, 2002It has been well known for more than 50 years that electric utilities in northern latitudes can have geomagnetically induced currents (GICs) flowing in their transmission lines and transformer ground points, and that these are caused by geomagnetic storms.

Statistical Properties of the Geomagnetic Field Variations and Geomagnetically Induced Currents
2019The relationships between variations of geomagnetic field and geomagnetically induced current (GIC) are studied using data from the station for registration of GIC in the electric transmission line and the IMAGE magnetic observatory. A highest correlation of GIC intensity (R > 0.7) is found with the field variability |dB/dt|, whereas the correlations ...

Geomagnetically Induced Currents over Iznik associated with Geomagnetic Storms
Geomagnetic storms are major disturbances in the near-Earth magnetic environment.  A geomagnetic storm can cause electrical power outages on the ground known as the geomagnetically induced currents (GICs). The GICs are directly related to the changes in the geomagnetic field over time and thus, they can be approximated by the time derivative ...Rana Betul Dag, Zerefsan Kaymaz

Rotor heating effects from geomagnetic induced currents
IEEE Transactions on Power Delivery, 1994The heating affects at the end-ring connection areas of the rotor due to the harmonic current generation of a saturating unit transformer from geomagnetic induces currents (GIC) on the transmission system have been calculated from observed data and from EMTP studies sponsored by the Electric Power Research Institute. These calculations show that damage

Geomagnetically Induced Currents (GICs) in Equatorial Region
2018 IEEE 8th International Conference on System Engineering and Technology (ICSET), 2018GICs is a ground end manifestation associated with the space weather perturbations that should be greatly taken into account by the society. Even though the GICs implication to the power system is not regularly happened, it can cause large scale of system failure.
