GB/T 20840.102-2020 Instrument transformers—Part 102:Ferroresonance oscillationsin substations with inductive voltage transformers
Abstract
This part of GB/T 20840 provides an introduction to the principles, examples, analysis, and suppression methods of ferromagnetic resonance in substations with electromagnetic voltage transformers. Electromagnetic voltage transformers and other non-linear inductive components can cause ferromagnetic resonance, which can cause great harm to electromagnetic voltage transformers and other equipment.
This part is suitable for guiding the calculation, simulation, experiment, measurement, and prevention and suppression measures of ferromagnetic resonance in power grids.
