Geomagnetic Induced Current Effect on SVC Operation

The Canadian Electricity Association also sponsored a study into the impact of geomagnetic currents (GIC) on static var compensators (SVC). In the middle of this study, a severe geomagnetic storm took out an SVC on the Hydro Quebec system which led to a system wide blackout. The report is:
