ND2805 Multiple Pulse Cable Fault Tester

Product Introduction

       As a leader in the field of power cable testing, our company continuously pursues perfection and strives for innovation in product development. The Cable Fault Pre-location Tester (Three-pulse method and Multiple-pulse method) is another masterpiece of the company, with technology reaching international advanced levels, breaking the monopoly of foreign companies in this field. The Cable Fault Pre-location Tester adopts internationally advanced arc reflection (three-pulse) technology, where all high-resistance fault waveforms appear as simple low-voltage pulse waveforms, making fault distance judgment easy and pleasant.

       The Cable Fault Pre-location Tester is used to detect high-resistance leakage faults, flashover faults, low-resistance grounding faults, and open-circuit faults in various power cables.
       Due to the instrument's adoption of the internationally advanced "Three-pulse Method" and "Multiple-pulse Method" technologies, combined with self-developed testing technology and high-voltage data signal processing devices, it possesses excellent cable fault waveform judgment capabilities and a simple and convenient operating system. This instrument has independent intellectual property rights.
       The advanced aspect of the Three-pulse Method is that it greatly simplifies the fault waveforms obtained on-site. It transforms complex high-voltage impulse flashover waveforms into easily interpretable waveforms similar to low-voltage pulse method short-circuit faults. This reduces the technical and experience requirements for operators, thereby significantly improving the accuracy of on-site fault judgment.
      Anyone can easily and accurately interpret waveforms and calibrate fault distances, achieving the goal of rapid and accurate cable fault testing. This greatly improves the success rate of fault testing. The overall technology of the Cable Fault Pre-location Tester is comparable to similar foreign products, and its performance-to-price ratio is significantly superior to both domestic and international counterparts.
