Insulator leakage current data compression based wavelet analysis

In this paper, wavelet analysis method is used to compress the leakage current data. Firstly, the modulus maxima denoising method was used to denose the data of the leakage current. And then high-frequency coefficients of the first layer was taken after the wavelet decomposition. Data points was sampled by the relationship between this high-frequency coefficient and the threshold given in the first. Finally, data points which had sampled was fitted. Experimental results show that the compression of wavelet analysis in this article is very effective.
