Cable Fault Locator 60km Traveling Wave Tester 400V Pulse 12.1 Touchscreen | XHGG501A2

The XHGG501A2 cable fault locator is a professional instrument for measuring the fault distance of power cables, based on the traveling wave method with an industrial-grade 12.1-inch touchscreen all-in-one computer. It is applicable to low-resistance, short-circuit, open-circuit and broken-circuit faults in power cables, high-frequency coaxial cables, street light cables and buried wires of various cross-sections and media, as well as high-resistance leakage and high-resistance flashover faults.

With a distance measurement range of at least 60 km, a 400V low-voltage pulse output and a 400MHz sampling frequency, the instrument achieves a minimum resolution of 0.1 m and a measurement error of no more than ±(0.5% × L + 1 m). It combines signal filtering, acquisition, data processing, graphical display and graphical analysis to complete cable speed measurement, cable length testing and cable fault distance testing in one portable unit.

The instrument supports both the low-voltage pulse method and the high-voltage flashover method, covering the full spectrum of cable fault natures from low-resistance faults to high-resistance flashover faults. Its built-in high-capacity lithium-ion battery and AC/DC dual power supply make it ready for field use anywhere.

Underground cable fault repair is a systematic process. The XHGG501A2 plays the key role in the pre-location stage, dramatically narrowing the search range before excavation begins.

The XHGG501A2 adopts the traveling wave method. In the low-voltage pulse method, a low-voltage pulse signal is applied to the cable under test; the pulse is reflected through the fault point, and the instrument processes the reflected signal to display a waveform. The coarse fault distance is determined by analyzing the reflected waveform.

In the high-voltage flashover method, a DC high-voltage supply or a high-voltage pulse signal source applies voltage to the faulty cable. When the voltage reaches a certain value, a sudden flashover discharge occurs at the fault point, generating a reflected signal that is received by a dedicated sampler and transmitted to the instrument for waveform analysis. The direct flashover method is mainly used for high-resistance flashover faults, while the impulse flashover method (universal method) is mainly used for high-resistance leakage faults.
