(57) Abstract: A detection method and system for insulation aging degree of superconducting cable. The detection method comprises: 
applying excitation voltages of different frequencies on a sample, and calculating a dielectric loss angle tangent corresponding to the 
sample at different frequencies by measuringthe voltage and current of the sample (S 1); and acquiring a detection result of the insulation 
aging degree of the sample according to the dielectric loss angle tangent corresponding to the sample at different frequencies (S2).
