Product Report on Power Cable Fault Tester

Product Report on Power Cable Fault TesterAfter multiple pulse generators, any complex high impedance waveform can be converted into a very familiar and easy to identify low-voltage pulse short-circuit fault waveform, greatly improving the functionality and utilization value of the instrument as well as convenient on-site environment operation. Especially for the increasing amount of buried cable data, a set of management software has been provided. The system testing consists of four parts: the system host, multiple pulse generator, fault locator, and cable routing instrument. It is used for testing various faults in power cables, searching for cable paths and burial depths, and daily maintenance and management of cable archives. And testing for faults in railway airport signal control cables and streetlight cables.

Product Report on Power Cable Fault TesterCharacteristics of LCGIIV power fault tester:
Adopting an industrial control embedded computer platform system, the entire system will consist of three parts: fault testing, path finding, and fixed-point testing. It is powered by lithium batteries, easy to carry, and convenient for testing.
◆ Equipped with a 12.1-inch LCD large screen and a touch mouse, integrated software for the full computer XP operating platform, bidding farewell to the era of cable instrument microcontrollers, and equipped with cable fault testing software and cable data management software
◆ Adopting a new USB communication interface, stable signal acquisition, and equipped with a laptop, dual control and dual display can be achieved. The host automatically selects the sampling frequency, with five frequencies for you to choose from: 0 low 6.25MHz, 0 high 100MHz, which can improve testing accuracy and meet the testing requirements of cables of different lengths.
The software implements automatic fault search, distance display, and dual cursor movement up to 0.15 meters, improving testing accuracy.
Powerful waveform processing and network service functions, the tested waveforms can be compressed and expanded freely, and two waveforms closer to the standard can be randomly displayed on the same screen for accurate comparison and analysis, reducing errors.
◆ Optional wireless network card can provide technical services for wireless internet access anytime and anywhere, providing users with timely and accurate waveform analysis and guidance for on-site testing, similar to expert guidance, making your work worry free.
◆ 20GB memory for various on-site waveforms and physical wiring diagrams, easily accessible with just a click. The cable data management software can provide comprehensive cable file management, providing reference and assistance for cable maintenance and positioning.
The key fixed-point instrument part, which is a replica, directly displays the distance between the tester and the fault point digitally, which is another innovation of similar fixed-point technology in China. It provides strong guarantee for quickly and accurately finding cable faults and reducing power outage losses.
The newly developed intelligent combination sampler replaces tedious on-site wiring, with intuitive waveform, easy analysis, isolation from high voltage, and safety features for the host and operators.
