Abstract:Cable fault detection is an important technology to find out the damaged cable,maintain the good condition of the circuit and ensure a normal status of life and work of electricity consumers such as the public andenterprises. This paper expounded a new method and a new system of cable fault detection by presenting their implementation,effect description and advantages on the basis of introducing current cable fault detection technologies . The method comprises the following steps:determining the spatial direction of the cable and finding out the location of damaged cable according to the spatial direction. The system comprises a control mechanism,a position mechanism and a detection mechanism. The method and the system make it more convenient,efficient and accurate to locate and repair the trouble spot of the cable,and are particularly suitable for the underground cable.
