Differential magnetometer method applied to measurement of geomagnetically induced currents in Southern African power networks

Matandirotya, Electdom; Cilliers, Pierre J.; Van Zyl, Robert R.; Oyedokun, David T.; de Villiers, Jean (AGU Publications, 2016-03-18)

Geomagnetically induced currents (GICs) in conductors connected to the Earth are driven by an electric field produced by a time-varying magnetic field linked to magnetospheric-ionospheric current perturbations during ...
Modeling geomagnetically induced currents in the South African power transmission network using the finite element method.

Matandirotya, Electdom; Cilliers, Pierre J.; Van Zyl, Robert R. (AGU Publications, 2015-03-24)

Geomagnetically induced currents (GIC) are a result of time variations of the geomagnetic field,which induce a geoelectric field at the Earth’s surface. Geomagnetic perturbations are enhanced during adverse space weather ...
