Development of instrumentation for measuring Geomagnetically Induced Currents (GICs) and effect of shield wires on GICs simulations

, 2021
Geomagnetically Induced Currents (GICs) are the result of rapid variations in the Earth's geomagnetic field and of the finite Earth's conductivity. Along grounded conducting structures such as transmission power networks, GICs can flow and, for extreme events, can be a threat to the power system normal operation.
