Figure 9From: Assessing the hazard from geomagnetically induced currents to the entire high-voltage power network in SpainMaximum values of GICs in each transformer as a consequence of an extreme geomagnetic storm. They correspond to a scenario for a return period of 100Â years. Here, we assume an impulsive event along the geomagnetic North. Vertical black lines indicate the 95% confidence levels.Back to article page
