We analyze variations in geomagnetically induced currents (GIC) and pulsations of the geomagnetic field latitudinal By component in the frequency range 1–20 mHz. The analysis is based on the data from GIC registration at the Kola Peninsula and magn

The impact of interplanetary (IP) shocks on the Earth’s magnetosphere can greatly disturb the geomagnetic field and electric currents in the magnetosphere-ionosphere system. At high latitudes, the current systems most affected by the shocks are the

A geoelectric field, voltages between grounding points of the Altai Republic power grid and geomagnetically induced currents (GIC) in power lines and grounding nodes were calculated in homogeneously conducting Earth’s crust model with the resistivi

It is well understood that geomagnetically induced currents (GICs) flow through the grounded neutrals of wye-connected transformers, generating harmonic currents that flow along frequency-dependent transmission lines. Harmonic currents affect protect

Geomagnetic disturbances (GMDs) give rise to geomagnetically induced currents (GICs) on the earth’s surface which find their way into power systems via grounded transformer neutrals. The quasi-dc nature of the GICs results in half-cycle saturation
