Ferromagnetic syntony is one kind of the self exciting oscillating phenomenon often happening in electric system ,overcurrent and overtension coming into being have caused very big effects on the electric system safety stabilizes operation。Saturated transformer iron core characteristic property is the cause arousing ferromagnetic syntony ,encouraging magnetoelectricity feeling characteristic property go into to the transformer is helpful to the syntony taking precautions against and removing ferromagnetic ,ensures that the electric system safety works thereby。Ferromagnetic article syntony phenomenon and their occurrence mechanism has carried out brief investigation and discussion ,the impact of ferromagnetic syntony over electric system has done brief analysis。The article takes the voltage mutual inductance implement opening a way on repeated side as fundamental model,nonlinearity encouraging magnetoelectricity feeling from iron core have started ,have built circuital mathematic model of syntony,the working spot having analysed ferromagnetic syntony ,the occurrence using the experiment way to have reproduced ferromagnetic syntony,measure the data having gained excitation characteristic property,the volt-ampere characteristic property having drawn excitation characteristic property pursues ,wields a graphical solution。Describing function law ,analysis have followed the data having carried out mathematical analysis ,being tied in wedlock an experiment ,have analysed different frequency。The number of windings ,the type wait for iron to encourage magnetoelectricity feeling characteristic property law under the core。And have submitted the suggestion preventing Yu from removing ferromagnetic syntony's。Keywords:Ferromagnetic syntony; Transformer; Excitation characteristic property; Mathematical analysis
