Scope

This part of GB/T20840 gives an introduction to the principle, examples, analysis and suppression methods of ferromagnetic resonance phenomena in substations with electromagnetic voltage transformers. Electromagnetic voltage transformers and other non-linear inductive components will cause ferromagnetic resonance, and ferromagnetic resonance will bring great harm to electromagnetic voltage transformers and other equipment. This section is applicable to guide the calculation, simulation, experiment, measurement and prevention and suppression measures of ferromagnetic resonance in the power grid.
