Recently,two incidents occurred in a company's power system,where voltage transformers were burned due to single-phase grounding faults on the lines,posing a threat to the safe and stable operation of the power system.Given the hazards of ferromagnetic resonance,a management plan suitable for ferromagnetic resonance in voltage transformers of power systems is proposed.Based on the existing secondary resonance elimination device,suppression measures combining primary resonance elimination devices with secondary resonance elimination devices are adopted.Through the management measures,the occurrence of ferromagnetic resonance has been suppressed and eliminated,ensuring the safe and stable operation of the company's power system.
