Zusammenfassung:Dielectric loss angle measurement has the error easily when noise ratio is low for short-term Fourier (STFT) interpolation harmonic analysis, easy to cover up real value. It shares the dielectric loss measurement method based on Wiener filtering of wavelet transform region. Via the excellent time-frequency analysis tools of wavelet transform, we pick-up basal frequency signal. And we calculate dielectric loss measurement angel by STFT harmonic analysis interpolation analysis method. Emulation result indicates that the method will increase measuring veracity more.
