| Session Abstract | ||
|
There has been growing concern in the electric power industry regarding the impact of Geomagnetically Induced Currents (GIC), or DC-quasi currents, which have caused, and may continue to cause, overheating of large numbers of power transformers in certain regions of the world, potentially leading to large-scale, long-duration system blackouts. This session presents the results of CIGRE WG A2.57 "Effects of DC Bias on Power Transformers" as well as the outcomes of recent research. | ||
