Product Introduction Underground cable fault locator is my company in order to cater to the advent of the era of power the power industry in the integration of many high-quality goods package the cable fault testing industry with the rapid development of the IT era as an opportunity the single chip microcomputer and laptop type of cable fault tester on the basis of embedded computer platforms to create suitable for cable fault testing industry characteristics of network cable fault testing service platform and systematic integration of the USB communication technology touch screen technology 3 g communications technology greatly improve the function of the use of the instrument and the use value and convenient site environment operation.Considering the increasing number of buried cables;The system satisfy the People's Republic of China power industry standard "DL/T849.1 ~ DL/T849.3-2004" electric power equipment dedicated testing equipment general technical conditions the system test by the host system multiple pulse generator the path of cable fault locator and instrument of four parts used in power cable fault test path the embedding depth of cable for airport and railway signal control cable and street lamp accurate test of cable fault. Thanks to the hard work of many engineers in the company the product has reached the international level especially since the whole set of devices has surpassed the world level in portability.The core technology of the multi-pulse method has changed the traditional testing method which has fundamentally solved the problem of high-resistance fault waveform reading that was difficult to solve previously. After multi-pulse generator any complex high-resistance waveform can be converted into a very familiar and easy to identify low-voltage pulse short-circuit fault waveform.It solves the problem that the user cannot recognize the complicated high resistance fault waveform for a long time and improves the level of the key rough measurement.
