XHDD503S Cable Fault Locator

Product Features The dual-probe positioning instrument uses the acoustic-magnetic synchronization method to generate electronic flashover with the help of an impulse discharge generator. The acoustic-magnetic signal of the electronic flashover wave is picked up and amplified by the corresponding probe to determine the exact location of the cable fault point. It has the function of indicating the fault direction. The dual probes are tested simultaneously to ensure the accuracy of the test results. It is used to accurately locate the fault point of the power cable.

Product description

Product Overview
The cable fault locator uses the principles of vibration sound pickup and electromagnetic induction to determine the specific location of the cable fault point. With the help of a high-voltage pulse generator, the fault point flashes over and discharges. The physical phenomena such as vibration waves, sound waves and electromagnetic waves generated by the flashover discharge of the fault point are picked up by the dedicated probe of the locator, amplified, processed, displayed and output by the cable fault locator, and finally the precise location of the fault point is determined by the tester's hearing and vision. That is, the precise positioning task of the cable fault point "directly above the cable, within the rough measurement range" is completed.
This locator is suitable for low-resistance, short-circuit, open-circuit and broken wire faults of power cables, high-frequency coaxial cables, street light cables, and underground wires of various materials with different cross-sections and different media, as well as high-resistance leakage and high-resistance flashover faults. The technical parameters meet the requirements of the standard "DL∕T 849.2 General Technical Conditions for Special Testers for Power Equipment Part 2: Cable Fault Locator".
