摘要
A method of detecting a current transformer saturation and an apparatus therefor are disclosed. A current transformer saturation detection device includes a multilevel filter bank and includes a wavelet transformer for filtering a current transformer secondary signal through the multistage filter bank and outputting the filtered signal as an output signal; A second high-pass filter for filtering and outputting a signal output from the wavelet transform unit; And a detector that detects a current transformer saturation using a peak of the filtered output signal.;
