Prediction of geomagnetically induced currents (GICs) flowing in Japanese power grid for Carrington-class magnetic storms [PDF]

open access: yesEarth, Planets and Space, 2021
Large-amplitude geomagnetically induced currents (GICs) are the natural consequences of the solar–terrestrial connection triggered by solar eruptions. The threat of severe damage of power grids due to the GICs is a major concern, in particular, at high ...

Measurements and Simulations of the Geomagnetically Induced Currents in Low‐Latitude Power Networks During Geomagnetic Storms

open access: yesSpace Weather, 2020
The issue of geomagnetically induced currents (GICs) on large distance ground‐based conductive systems is a global space weather concern nowadays. The low‐latitude power grids are becoming more vulnerable to GICs hazards due to their increasing scale and

Repair bond strength and degradation of glass ionomer cements after mechanical and chemical challenges

open access: yesBrazilian Journal of Oral Sciences, 2020
Aim: Little is known about the reparability of glass ionomer cements (GICs) after storage in acid environments. The aim of this study was to evaluate the solubility and repairability of GICs immersed in acid solutions and subjected to brushing.

Superposed Epoch Analyses of Geoelectric Field Disturbances in Japan in Response to Different Geomagnetic Activities

open access: yesSpace Weather, 2022
An increase in geomagnetically induced currents (GICs) is an inevitable result of geomagnetic field disturbances, and is harmful to the power grid, in particular, at high latitudes.

The Correspondence Between Sudden Commencements and Geomagnetically Induced Currents: Insights From New Zealand

open access: yesSpace Weather, 2022
Variability of the geomagnetic field induces anomalous Geomagnetically Induced Currents (GICs) in grounded conducting infrastructure. GICs represent a serious space weather hazard but are not often measured directly and the rate of change of the magnetic

Power system harmonic analysis with real geomagnetically induced current from the 2003 halloween storm

open access: yesScientific African, 2023
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.
