How to identify the type of cable fault? A: Correctly judging the type of cable fault is the first step to find the fault. The required instruments are a high resistance meter (shake meter) and a multimeter. The specific steps of the cable fault tester manufacturer are divided into two steps: Step 1: How to judge the type of cable fault? A: Correctly judging the type of cable fault is the first step to find the fault. The required instruments are a high resistance meter (shake meter) and a multimeter. The specific steps of the cable fault tester manufacturer are divided into two steps: the first step: measure the relative-to-ground insulation resistance and the phase-to-phase insulation resistance, and identify the faulty phase of the cable; the second step: check whether the cable conductor is broken.

(1) When measuring the relative-to-ground insulation resistance and the phase-to-phase insulation resistance, first use a high resistance meter (shake meter) to measure the insulation resistance between A to ground, B to ground, C to ground, AB, BC, and CA respectively, and find out Phases with unacceptable insulation resistance values. If the measured value of the high resistance meter (shake meter) is 0M ohm, then use the multimeter to retest. (2) Conduct a conductor continuity test to check whether the cable conductors are disconnected, first short-circuit and suspend the three-phase conductors at the remote end, and measure the loop resistance of the interphase conductors with a multimeter at the near end. Zero ohm means there is no wire breakage fault; if there is a value of zero, there is a wire breakage fault at the same time.
