Massive eruptions on the sun can lead to disturbances in the earth's surrounding magnetic field. These, in turn,can drive excess electric currents in power transmission systems which heat transformers and may eventuallylead to system failure. In this project, we will investigate the relationship between transformer failures inAltalink's power transmission system and geomagnetic disturbances. The results of the study will enableAltalink to begin to address forthcoming changes to reliability standards which will require power companiesto take account of geomagnetic hazards in their risk assessment and mitigation planning.

太阳上的大规模喷发会导致地球周围磁场的扰动。反过来，这些会在输电系统中驱动过多的电流，从而使变压器过热，最终可能导致系统故障。在这个项目中，我们将调查Altalink输电系统中变压器故障与地磁干扰之间的关系。这项研究的结果将使Altalink能够开始处理即将对可靠性标准进行的变化，这将要求电力公司在其风险评估和缓解规划中考虑到地磁危害。
