Geomagnetic Disturbances: A Danger to the Power Grid

In 1989, the Québec grid collapsed as equipment protection relays tripped in a cascading sequence of events. Six million consumers were left without power for up to nine hours. The cause of this major outage was a geomagnetic disturbance (GMD).

Geomagnetic disturbances occur during solar storms caused by charged particles, that are ejected by the sun toward Earth. These high-energy particles, known as a coronal mass ejection, can travel to Earth in 14 to...
