摘要（英）：

The invention discloses a DC cable insulation state judgment method. The method comprises the following steps: acquiring an electric signal of a cable; acquiring a feature parameter according to the electric signal; acquiring feature parameter weight; and judging a cable insulation state according to the feature parameter and the feature parameter weight. Through the DC cable insulation state judgment method provided by the invention, the feature parameter and the feature parameter weight are acquired through the electric signal of the cable, the cable insulation state is judged according to the feature parameter and the feature parameter weight without changing a running state of the cable; the testing is convenient, an operation of contacting electrified equipment is avoided, the detection security is high, and the judgment accuracy is high.
