What specific risk do Geomagnetically Induced Currents pose to electrical infrastructure?
Answer
They act as a direct current bias that saturates and damages power transformers
During a geomagnetic storm, the fluctuating magnetic fields induce electrical currents in long-distance conductors like high-voltage power lines. These currents, known as Geomagnetically Induced Currents, do not function like the alternating current standard of the grid. Instead, they act as a direct current bias that can saturate the iron cores of large power transformers. Once saturated, these transformers can overheat and sustain serious physical damage, potentially leading to widespread, long-term power grid failures.
