| Abstract: | In this paper, a frequency-dividing resonance fault of capacitive voltage transformer (CVT) happened in Hunan province is described at first. Then the principles and conditions of the resonance of CVT are expounded and calculated. At last, the preventive and solving measures, lowing the working magnetic flux density, increasing the k value and proper selecting of damper, are proposed. |
