地磁

Geo-magnetically induced currents are triggered by geomagnetic storms, the frequency of which ranges from 0.001 Hz to 0.100 Hz. GIC will cause DC bias saturation of transformers, unnecessary relay tripping and blackouts.

中文摘要：磁暴在输电线路引发的地磁感应电流频率为0.001～0.100 Hz，这种准直流的GIC将造成变压器直流偏磁饱和，引发电网保护误动作和停电事故。
