Leveraging its profound scientific research capabilities, high-quality product portfolio, and professional service expertise, the company has distinguished itself amidst the wave of intelligent transformation sweeping through the power industry. It has emerged as a trusted partner for domestic and international stakeholders in the power sector, harnessing technological innovation to inject powerful momentum into the industry's high-quality development. As a high-tech enterprise integrating R&D, manufacturing, sales, and service, XZH TEST leverages the technical resources of renowned institutions—such as Xidian University and Xi'an Jiaotong University—as well as research institutes like the Xi'an High Voltage Apparatus Research Institute and the Wuhan High Voltage Research Institute. Focusing on the core testing requirements of the power industry, the company specializes in the R&D and manufacturing of high-voltage testing equipment and precision instrumentation. The company's core product portfolio encompasses a diverse range of high-quality power testing equipment series, including cable fault locators, high-voltage pulse generators, partial discharge detectors, and ground resistance testers. These products are widely utilized across every segment of the power industry—spanning power generation, transmission, distribution, and consumption—as well as in research institutions and among power equipment manufacturers, enabling the provision of comprehensive, integrated power testing solutions. Technological innovation constitutes the core competence of XZH TEST and serves as the primary driving force behind the company's sustainable growth. The company has established a dedicated R&D team that remains consistently focused on addressing critical technical pain points within the industry, continuously driving the iterative upgrading of its product portfolio. Notably, the company's independently developed XHGG series of cable fault testers—which integrate industrial-grade integrated circuits with modern computer technology—enable rapid flash testing and precise localization of cable faults. Furthermore, the XHDD503 series of acoustic-magnetic synchronous pinpointing instruments leverages core technologies such as acoustic-magnetic time-difference localization and noise reduction to efficiently resolve industry-wide challenges regarding the inaccurate localization and inefficient troubleshooting of buried cable faults. Additionally, the XHHV series of high-voltage pulse generators—which consolidate functions such as DC high-voltage sources and energy-storage capacitors into a single unit—feature a compact design and user-friendly operation; these devices have successfully replaced traditional, heavy-duty testing equipment, thereby significantly enhancing the efficiency of power system testing operations. Concurrently, XZH TEST has entered into a strategic partnership with the 29th Metrology and Testing Center of the Machinery Industry. This collaboration facilitates comprehensive third-party inspection and calibration services for power testing equipment, ensuring that every product adheres to rigorous industry standards and providing users with reliable assurance regarding the accuracy and integrity of their testing operations.
10kV cable fault location 2026-03-11 In the city's power grid, a 386-meter-long 10kV power cable suddenly malfunctioned. One end connects to a ring main unit, and the other to a distribution cabinet; it's buried deep underground. Preliminary tests by on-site personnel showed that the insulation of phase B was only 0.04MΩ, while the insulation of the other phases was intact. Where exactly was the fault? Did they have to excavate the entire 386-meter length? Insulation test: An XHMR-5000V insulation resistance tester was used to perform a phase-to-ground insulation test on phase B. At 5000V, the resistance was 0.04MΩ (270V), while the other phases reached GΩ after 15 seconds. The conclusion is that phase B is faulty to ground. Total length verification: First, using the XHGG502 cable fault tester, the total length of the cable was measured to be approximately 386.5 meters using the low-voltage pulse method. For the B-phase ground fault, we used the high-voltage flashover method for coarse measurement. After connecting the XHHV535-4Z high-voltage pulse generator, the voltage steadily increased to 10kV. As the time relay precisely closed the gap, the instrument clearly captured the standard reflected waveform at the moment the fault broke down. The waveform showed the cable fault distance to be 164.1 meters. The fault range was suddenly reduced from 386.5 meters to this small area. Since the route was partially known and guided by cable stakes, we primarily relied on a 503 locator for precise positioning. Proceeding along the route to the 164.1-meter mark, we applied high voltage again when we reached the vicinity of the construction site. When the voltage reached approximately 10kV, a clear, rhythmic discharge sound emanated from underground! The source of the sound was precisely near the roughly measured distance. Upon closer inspection, we found that the cable had been exposed due to previous construction work, and the fault point was clearly breached and exposed to the air.
