POWER GRID OUTAGES. “In power grids, these geomagnetically induced currents cause saturation of transformers, which tends to distort and increase the excitation current. The excitation current in turn induces harmonics in the electricity, unwanted relay trippings, large reactive power consumption, or voltage fluctuations, which can lead to black-outs or to permanent damage of transformers.”
