The cable fault location instrument XHDD503C uses the acoustic and magnetic synchronization method to determine the power cable fault point. The electronic flashover is generated by the impact discharge generator, picked up and amplified by the corresponding probe, and the precise location of the fault point is determined by auditory and visual judgment. It is a device that completes the precise positioning of the cable fault point within the rough measurement range and collects the acoustic and magnetic time difference. It integrates positioning technology, path-assisted testing and other technologies, providing multiple test modes and rich and diverse prompt information to efficiently and accurately complete cable fault location.

This fixed-point instrument is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flashover.

All accessories

The XHHV535-4TS high voltage pulse generator can be used impulse discharge and withstand voltage test in low and high voltage cable fault test. High-precision test cable fault sampling waveform module and small transformer are installed inside, which can truly achieve the effect of not being damaged by impact, and it also has the functions of automatic timing impact, manual impact and withstand voltage test.

This device integrates a high-voltage DC source, an energy storage capacitor, a discharge ball device, an automatic discharge device, and a voltage level switching device into a cart-type high-end experimental instrument. It is a trolley-type high-end experimental instrument. The equipment completely solves the problems of ease of use, portability, safety and reliability of traditional experimental devices.

When the XHHV535-4TS trolley-type high-voltage pulse generator is in use, after selecting the function switch, press the start button to perform high-voltage boosting work. After use, press the stop button, and the internal system will automatically release the remaining high voltage on the accumulator.

The high voltage surge generator also has the function of zero-start protection, which can make the operation of the device more safe and reliable. It has super short-circuit protection function, which can make the high-voltage output work directly to the ground. With three-gear voltage range and capacitance capacity switching function, users can choose different equipment voltage adaption gears according to different cable voltage needs, making the test process easier.

2024 new update-The power socket, fuse holder, and signal socket have been moved to the side, making it more convenient to use when you put the device in the car to detect cable faults.
