XHDD503C
The cable fault location instrument 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 cable fault pinpointer 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.
