Product Description
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.
