Data-driven transfer functions from differential magnetometer measurements to enhance GIC model validation capability: A case study in the Spanish power grid

Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer neutrals. Prediction models, used to foresee the amplitudes and waveforms of those...

The differential magnetometer method (DMM), based on dual magnetic measurements, one under a power line and the other at a reference location a few hundred meters away, is used to locally validate those models by indirectly measuring the GIC.
