Cable analysis method and system based on impedance spectrum

The invention discloses a cable analysis method and system based on an impedance spectrum, and the method comprises the steps: obtaining an impedance spectrum signal of a cable, carrying out the analysis based on the impedance spectrum signal through a cable analysis model, obtaining the fault type of the cable, and building a feature interaction space during the signal analysis. The time domain signal and the frequency domain signal are interacted, so that the implicit information in the impedance spectrum signal can be extracted, and the extracted global features and local features can accurately represent the fault condition of the cable. The fault category of the cable is obtained based on the global features and the local features, the fault category of the cable can be accurately analyzed, and the accuracy of cable fault category analysis is improved. The accuracy of cable analysis model feature extraction, feature fusion and fault classification is high, and then the accuracy of cable fault categories
