Time Domain Feature Extraction Technology of Partial Discharges Based on the Envelope of UHF Signal

摘要：

　　This paper proposed a method to extract the time-domain features of ultra-high frequency(UHF)signals regarding the partial discharges(PD).Using the Hilbert transform,the envelope of a PD signal can be solved since the low-frequency signals modulated by high-frequency signals can be demodulated through Hilbert transform.Then the characteristic parameters of some key time domains would be obtained from the extracted envelope signal.An experimental platform for the detection of artificial insulation faults was designed and established.Three types of typical PD signals were generated and used for the verification of our presented algorithm.The result shows that different types of PDs could be accurately recognized.
