在电力行业中存在一些误解，认为地磁感应电流（gic）会对大多数大中型电力变压器造成严重的过热损坏。由于gic的性质，大多数电力变压器不会因为它们而经历破坏性的过热。本文提出了GICs的真正问题，即无功功率吸收的增加和注入电力系统的电流谐波的结合可能导致电网稳定性受损。
There has been some misconception in the electric power industry that geomagnetically induced currents (GICs) can cause significant overheating damage to the majority of medium and large power transformers. Because of the nature of GICs, the majority of power transformers would not experience damaging overheating because of them. This article presents the real issue with GICs, which is that the combination of the increase of reactive power absorption and injected current harmonics into the power system could result in compromised grid stability.
