This paper expounds the principle and conditions of ferromagnetic resonance generation, and analyzes the ferromagnetic resonance accident of Hetan substation. The article explains the concept of “illusive grounding” caused by ferromagnetic resonance, combined with the Peterson curve. The conditions for the generation of ferromagnetic resonance are analyzed, and the common measures to eliminate ferromagnetic resonance are given.
