Technical specification
Impulse generator
Surge voltage generators enable accurate location of high resistance, low resistance and intermittent faults on high, medium and low voltage cables.
Output voltage is continuously adjustable in the ranges 0 - 8 kV, 0 - 16 kV and 0 - 32 kV.
Discharging of high voltage capacitors into the faulty cable can be made continuously or cyclically via surge switch. When the instrument is switched off, the connected cables and the internal surge capacitors are automatically discharged separately from each other.
Features
High surge voltage up to 32 kV

Cable fault pinpoint locator
The system equipped with accessories include a receiver, headphone, proble, A frame.
With these accessories, it can perform cable fault precise location and sheath fault location.The cable fault locator uses the principles of vibration pickup and electromagnetic induction to determine the specific location of the cable fault point. A high-voltage pulse generator is used to cause flash over discharge at the fault point. Physical phenomena such as vibration waves, sound waves, and electromagnetic waves generated by the flash over discharge at the fault point are picked up by a special probe of the pointing instrument, amplified, processed, displayed, and output by the cable fault pointing instrument. The precise location of the fault point is determined by the tester's hearing and vision. That is, the task of accurately locating the cable fault point "directly above the cable and within the range of rough measurement" is completed.
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 flash over fault.
