Anti Noise Processing for UHF Partial Discharge Detection Based on Fractional Order Noise Filter
In the built-in ultra-high frequency partial discharge detection,there is high-frequency composite noise generated by communication and superposition,which interferes and masks the partial discharge signal,making it difficult to obtain accurate partial discharge waveform.Combined with the characteristics of the fractional noise filter and the filtering principle,this paper focuses on the fractional order noise filter and proposes a noise control method for ultra-high frequency partial discharge detec-tion based on the fractional order noise filter.The effectiveness,stability,and reliability of this method in controlling high-fre-quency composite noise in ultra-high frequency partial discharge detection have been verified through finite element simulation and experiments.
