ND2803 Cable Fault Tester

Product Introduction

       The smooth operation of wired communication and power transmission relies on the normal functioning of cable lines. Once a line fault occurs, failure to promptly detect and eliminate the issue can result in significant economic losses and adverse social impacts. Therefore, the cable fault tester is an essential tool for maintaining various types of cables.

       The Intelligent Cable Fault Tester employs multiple fault detection methods, utilizing advanced electronic technologies and components, computer technology, and specialized electronic techniques. Combined with our company's extensive experience in developing cable testers, it represents a high-tech, intelligent, and fully functional new product.

       The Intelligent Cable Fault Tester is a comprehensive cable fault detection instrument. It can test high-resistance flashover faults, high and low resistance grounding, short circuits, cable breaks, poor contact, and other faults. When equipped with an acoustic pinpointing device, it can accurately determine the precise location of the fault. It is particularly suitable for testing various types of power cables (with different voltage levels) and communication cables.

Product Features

☆、Comprehensive functionality, safe, fast, and accurate fault testing. The instrument uses low-voltage pulse and high-voltage flashover methods to detect various cable faults, especially flashover and high-resistance faults, without the need for burning through. When equipped with an acoustic pinpointing device, it can accurately determine the fault location;
☆、High testing precision, with high-speed data sampling technology. The A/D sampling speed is 100MHz, providing a resolution of 1m and a blind zone of 1m;
☆、High level of intelligence, test results are automatically displayed as waveforms and data on a large LCD screen, making fault judgment intuitive. It features a full Chinese menu display, requiring no specialized training for operators;
☆、This cable fault tester has waveform and parameter storage and recall functions, using non-volatile components to prevent loss of waveforms and data after shutdown;
☆、Dual-trace display function allows comparison between the test waveform of a faulty cable and a normal waveform, aiding further fault judgment;
☆、Waveform scaling function enables changing the waveform比例 for precise testing;
☆、Arbitrary adjustment of dual cursor positions, directly displaying the absolute or relative distance between the fault point and the test point;
☆、Ability to modify propagation speed according to different cables being tested;
☆、Compact portable design with built-in rechargeable battery, convenient for carrying and use.
