Detailed Product Description: | The reasons for the failure of wire and cable wire and cable equipment wire and cable testing with the power, the development of the energy industry, all kinds of cables are increasingly applied to the production of all areas of life, and are generally buried underground or into the cable trench laying cables at after failure, and how quickly and accurately find the point of failure, and as soon as power is restored, long plagued our problems. Both high voltage cable, low voltage cables, construction and installation, running often fail due to short-circuit, over-load operation, insulation aging or external force causes. Cable fault can be summarized as grounding, short circuit, broken into three categories, mainly the following aspects: (1) three-core cable core or two cores grounded fault type. ② two-phase short circuit between the core wire. ③ three-phase core line completely short-circuited. The ④ phase core wire disconnected or multiphase break. Direct measurement with a multimeter for direct short circuit or disconnection fault judgment, direct short circuit and ground fault the megger telemetry core wire insulation resistance or core line-to-ground insulation resistance, based on its resistance to determine the type of fault. |
