Induction currents in HVAC networks under Earth magnetic field disturbance [PDF]

, 2012
Виконано аналіз збурення магнітного поля Землі та його вплив на енергосистему. Розглядається механізм утворення геомагнітних індукційних струмів ГІС, які можуть негативно впливати на комунікації, у тому числі й на дальні високовольтні електричні мережі.

Assessment of the Geomagnetically Induced Current (GIC) at Low Latitude Region based on MAGDAS Data

Journal of Physics: Conference Series, 2019
The geomagnetically induced current (GICs) impact is no longer concentrated at high latitude region strictly. The objective of this study was to extend the GICs observation conducted at equatorial region using geomagnetic data extracted from magnetometer installed at Langkawi National Observatory (LNO), Malaysia for the long-term analysis involving the

The Geomagnetically Induced Current Extremal Values Estimation Based on Baygazan Magnetical Station Data

Russian Journal of Earth Sciences
Based on the Baygazan magnetic station data, geomagnetically induced currents (GIC) in the 500 kV Sayano-Shushenskaya HPP (SSHPP) – Novokuznetsk substation power line were simulated during very strong and extreme magnetic storms (planetary geomagnetic ...

Modified GIC Estimation Using 3‐D Earth Conductivity

Space Weather, 2020
Geomagnetically induced currents (GICs) are quasi‐direct current (DC) electric currents that flow in technological conductors during geomagnetic storms. Extreme GICs are hazardous to man‐made infrastructure. GICs enter and exit the technological systems,

Space storms as natural hazards [PDF]

, 2008
Eruptive activity of the Sun produces a chain of extreme geophysical events: high-speed solar wind, magnetic field disturbances in the interplanetary space and in the geomagnetic field and also intense fluxes of energetic particles.

Geomagnetically induced currents in a Norwegian transformer station [PDF]

, 2022
This report considers measurements of geomagnetically induced current (GIC) and comparison to recorded variations in the geomagnetic field (dB/dt). The GIC-sensors were installed in the neutral point of a 420 kV transformer located in Mid-Norway in 2019.
