Description

technical field [0001] The invention relates to the technical field of cable fault detection, in particular to a cable fault detection device and a testing method. Background technique [0002] Various types of cables are not only widely used in the fields of electric power and communication, but also widely used in various fields of national economic development such as coal mining, metallurgy, chemical industry, and transportation. Wide application also requires better detection and maintenance technology as a guarantee. Since the cables are usually suspended in the air or buried underground or underwater, the fault points of the cables are relatively hidden, and it is relatively difficult to find and maintain them. The above characteristics of the cable fault point put forward high technical requirements for the cable fault detection instrument, how to accurately, quickly and economically search the cable fault point has become an important technical problem. [0003] C...
