Cable fault detection instrument Cable fault type and judgment The cable fault detection instrument, regardless of the high-voltage cable or low-voltage cable, is often caused by faults such as inspection and blocking, overload operation, insulation aging or external force wear during groundbreaking and operation. Cable faults are divided into three categories: grounding, blocking, and disconnection. The three-core cable fault categories are indispensable: one or two cores are in contact; the neck is stuck between the two-phase cores; the three-phase cores are completely blocked; the one-phase core is broken or multi-phase is broken.
For direct congestion or disconnection faults, the multimeter can be used to measure and judge all the time. For non-straight green lights and battery connection faults, use a megohmmeter to remotely measure the insulation resistance between core wires or the insulation resistance of core wires to ground, which can be clearly identified according to the resistance value.
