frequently occurs in neutral isolated distribution net and neutral grounded networks.The consequent overvoltage and overcurrent do great harm to the power equipment
and result in a series of stabilization and safety problems.In this paper
the reason of the phenomenon is discussed.Besides
the wavelet toolbox in MATLAB is also used to analyze the ferromagnetic resonance caused by single-phase earthed fault in a 10 kV neutral isolated power system
detect the time of the fault and determine the resonance frequency.Simulation results show that the method is quite effective.
