Ferromagnetic Resonance Analysis and Automatic Detuning of 35 kV Electromagnetic Voltage Transformer
Ferromagnetic resonance is a common phenomenon in ineffectively grounded power system,which seriously endangers the safe and reliable operation of the system.In this paper,the reasons of ferromagnetic resonance in substation are described in detail through an exemplary case,and the measures to prevent the occurrence of resonance or reduce its amplitude are studied.
