| Abstract: | The causes and suppression measures in common use of ferromagnetic resonance in 10 kV neutral ungrounded system are analyzed. Ferromagnetic resonance caused by the single- phase earth fault which frequently occurs and its corresponding suppression treasures are discussed. The structure of a new resonance eliminator is put forward and its working principle is studied. Then the validity of proposed scheme is verified by EMTDC/PSCAD - based simulation results. |
