First, the cable fault tester manufacturers overview:
As a leader in the field of power cable testing, our company constantly strives for perfection and innovation in product development. The cable fault pre-positioning test host (three-pulse method) is another masterpiece of the company. The technology has reached the international advanced level, breaking the monopoly of foreign companies in this field, and the cable fault pre-positioning test host adopts horizontal arc reflection (three pulses). Technology, all high-impedance fault waveforms are presented as simple low-voltage pulse waveforms, and the fault distance is judged easily and pleasantly.
The cable fault pre-positioning test host is used to detect high resistance leakage faults, flashover faults, low-resistance grounding, and open circuit faults for various power cables.
As the multi-pulse cable fault tester adopts the internationally advanced "three-pulse method" technology, combined with independently developed test technology and high-frequency high-voltage data signal processing equipment, it has the best ability to judge the waveform of the cable fault and the easiest Convenient operating system. This instrument has independent intellectual property rights. It is the first domestic "triple pulse method" cable fault tester that has been successfully developed in China.
The advanced feature of the three-pulse method is to greatly simplify the fault waveform measured in the field. The complex high-voltage impulse flashover waveform becomes a very easy to interpret short-circuit fault waveform similar to the low-voltage pulse method. Reduced technical requirements and experience requirements for operators. Therefore, the judgment accuracy of on-site faults is greatly improved. Anyone can conveniently and accurately interpret the waveform, calibrate the fault distance, and achieve the purpose of quickly and accurately testing the cable fault. The failure test success rate can be greatly improved. All traditional cable meters in the country cannot match it. Cable fault pre-positioning test host's overall technology can be comparable to similar foreign products, its performance and price ratio is better than similar products at home and abroad.
Second, cable fault tester manufacturer features and features:
