The ZMY-2000 Direct Buried Cable Fault Tester, developed by the company using advanced concepts, is particularly suitable for rapid and accurate location of cable insulation faults, open circuits, and short circuits, as well as for locating and measuring the depth of underground cable paths online or offline. The newly crafted device is especially designed for fast and accurate fault location of direct buried power cable faults and underground cable faults.
It is designed based on electromagnetic induction method combined with communication principles. It incorporates more user-friendly designs, with a large LCD screen displaying signal strength (digital, bar graph, arrow, and sound) prompts, making it easy for operators to determine the underground position of the cable and the fault point. One person can complete all operations.
It can be used both for locating underground cable paths (energized or de-energized) and for finding direct buried cable faults. It can accomplish tasks that previously required multiple instruments. Traditional cable fault locators require high-voltage test equipment, must use AC power, have complicated wiring, and often leave testers helpless when encountering metal dead ground faults. The ZMY-2000 Direct Buried Cable Fault Locator changes the traditional concept of cable fault location: no high-voltage test equipment needed, no AC power required, no waveform analysis, simple and clear wiring, and easy to use at first sight.
In the past, to locate underground cable paths, we had to de-energize the cable for testing, but some operating cables cannot be de-energized. Using the ZMY-2000 Direct Buried Cable Fault Locator can easily solve the problem of locating energized cable paths. The ZMY-2000 can also directly locate the path of 50Hz operating cables.
