Free metal particle was a common impurity in fault DC bushing, which was produced while its operation. This paper mainly focused on analyzing the typical fault of DC bushing, morphology and motion characteristic of mental particles. A experiment platform was built to study the discharge characteristic, and the result consistently with analysis was obtained. The mental particles would aggregate and accumulate due to the unevenly temperature distribution, and lead to distortion of electric field. The location and width of mental particles would have impact on discharge characteristic. The research result could be used as structural optimization and design of DC bushings, which was worth a further study both in academic and engineering application.
