Product IntroductionProduct Introduction
The underground cable fault locator is a networked cable fault testing service platform developed by our company to cater to the arrival of the power industry and the power era. It integrates many high-quality solutions in the cable fault testing industry and takes the rapid development of the IT era as an opportunity to abandon single-chip microcontrollers and laptop type cable fault testers. Based on an embedded computer platform, it creates a suitable network cable fault testing service platform for the characteristics of the cable fault testing industry. It systematically integrates USB communication technology, touch screen technology, 3G communication technology, greatly improving the instrument's functionality, utilization value, and convenient on-site environment operation. Considering the increasing number of buried cables nowadays; The entire system meets the general technical requirements for specialized testing instruments for power equipment in the power industry standards of the People's Republic of China, DL/T849.1~DL/T849.3-2004. The system testing consists of four parts: the system host, multiple pulse generators, fault locator, and cable routing instrument. It is used for testing various types of faults in power cables, searching for cable paths and burial depths, and accurately testing faults in railway airport signal control cables and street lamp cables.
The underground cable fault locator is the result of our company's continuous exploration over the years to catch up with the world's advanced level of similar products. It is the technical crystallization of the hard work of multiple engineers within the company. This product has achieved parity with international standards, especially in terms of portability, the entire set of equipment has surpassed similar levels in the world. The core technology of the multiple pulse method has changed the traditional testing method, fundamentally solving the previously difficult problem of reading high impedance fault waveforms. Through multiple pulse generators, any complex high impedance waveform can be transformed into a very familiar and easy to identify low-voltage pulse short-circuit fault waveform. Solved the long-standing problem of users not recognizing complex high impedance fault waveforms, and significantly improved the critical level of rough measurement.
Product nickname: Fully intelligent multiple pulse cable fault tester, multiple pulse cable fault tester, underground cable fault locator

Product FeaturesProduct Characteristics
- 1. Adopting an industrial control embedded computer platform system and an industrial grade usage environment, it achieves extremely strong stability. Lithium battery power supply, convenient for on-site testing
- 2. Adopting a 12.1-inch large screen touch system and integrated software on the full computer XP operating platform, bidding farewell to the era of cable instruments and single-chip microcontrollers
- 3. Adopting a new type of USB communication interface, stable signal acquisition, and equipped with a laptop, dual control and dual display can be achieved. The host can automatically select five sampling frequencies from a minimum of 6.25MHz to a maximum of 100MHz, which can meet the testing requirements of cables of different lengths and reduce rough measurement errors
- 4. The software implements automatic fault search, distance display, and false card alarm functions. The dual cursor movement can be precise to 0.15 meters, and the waveform can be compressed, expanded, and overlapped at will. Ten low-voltage pulse waveforms are randomly displayed on the same screen for you to choose from overlapping positioning, improving testing accuracy and reducing errors
- 5. Supporting newly opened 3G communication terminals or wireless network cards, dedicated 3G software enables expert remote on-site real-time testing technology services. Experts remotely control user hosts to provide timely and accurate waveform analysis and communication guidance for on-site testing, allowing you to work worry free
- 6. The key precise fixed-point instrument part, which directly displays the distance between the tester and the fault point digitally, is another innovation of similar fixed-point technology in China, providing strong guarantee for quickly and accurately finding cable faults and reducing power outage losses
- 7. The multiple pulse method generator discharges once and generates ten low-voltage pulses. The short-circuit waveform is intuitively superimposed and easy to analyze. The multiple pulse generator has a small volume and weighs only 5kg, truly realizing the portability of the entire equipment
- 8. Three types of high-voltage discharge parts are available for users to choose from, with a high-frequency high-voltage power supply of 8.9kg replacing the 65kg test transformer and operation box, filling a gap in China
