Recently, Song Gong, an after-sales staff of Wuhan Jindian Technology, came to Taiyuan, Shanxi at the invitation of customers to provide after-sales training services for a set of cable fault testers purchased in our company!

    product description

    NR4100 series cable fault tester is a comprehensive set of cable fault detection instruments. It can test high-resistance flashover faults, high-low-resistance grounding, short-circuit, cable disconnection, poor contact and other faults of the cable. If equipped with an acoustic measuring method, the precise location of the fault point can be accurately determined. The instrument can test various types of power cables (voltage level 1KV ~ 35KV) and local telephone cables, FM communication cables, coaxial cables and metal overhead lines for short-circuit, grounding, high-resistance leakage, high-resistance flashover faults and cables It can also test the length of the cable and the propagation speed of the radio wave on the cable.

    main feature

     The test fault is safe, rapid and accurate; the instrument adopts the low-voltage pulse method and the high-voltage flashover method to detect various faults of the cable, especially the flashover and high resistance faults of the cable can be directly tested without burning through; The measuring point instrument can accurately determine the precise location of the fault;

     The instrument adopts high-speed data sampling technology, A/D sampling speed is 100MHz, so that the instrument reading resolution is 1m, and the detection blind area is 1m;

     The test results are automatically displayed on the large-screen LCD screen with waveforms and data, and the fault diagnosis is intuitive; and it is equipped with a full Chinese menu display operation function, which does not require special training for operators;

    Since there is no fault point at the project site, Song Gong communicated with the client to carry out simulation teaching this time.

    First of all, Song Gong gave a detailed introduction to the equipment, explained the theoretical knowledge of equipment principles, equipment composition, testing methods, etc., and then formally launched simulation teaching.

    Before testing the cable fault, Song Gong measured the phase-to-ground and phase-to-phase insulation resistance at one end of the cable, and judged the fault type according to the resistance value. Then choose different test methods according to the type of failure. In the teaching process, the operation precautions are emphasized one by one, and the fault judgment method is explained in detail.

    After Song Gong patiently explained, the customer also simulated the equipment. During repeated drills, customers gradually became familiar with how to use the equipment. And praised Song Gong's professional service.

     Providing the perfect service experience for our customers has always been our service tenet. In the future, Wuhan Jindian Technology will continue to provide every customer with better after-sales service with a professional and dedicated service attitude.
