Product Details
The XHHV535-2TSB cable fault location system is used to detect the main insulation
fault of power cables with voltage levels of 35kV and below and
calibrate the cable length. This system consists of two parts: a
cable fault tester and a high-voltage pulse generator.
The cable fault tester adopts a simple operating software
interface, centralized control by a single-chip
microcomputer,touch-type operation, and a built-in large capacity
lithiumion battery. It is stable, reliable, and easy to use. An
independent power supply and power supply system are used to
prevent power supply interference during impact discharge.
This cable fault test system 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 flash over faults.

XHDD503E Cable fault pinpointer
XHDD503E cable fault pinpointer uses the acoustic-magnetic
synchronization principle of vibration 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 is flashed and discharged. The physical phenomena such as
vibration waves, sound waves and electromagnetic waves generated by
the flash over discharge of the fault point are collected by the
dedicated probe of the positioning instrument. After intelligent
processing by the host, the fault distance and output fault sound
are displayed. Finally, the precise location of the fault point is
judged 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.
XHDD503E cable fault pinpointer is suitable for low-resistance,
short-circuit, open-circuit, and broken-wire faults of various
power cables, coaxial cables, and low-voltage cables and wires with
different voltage levels, different cross-sections, and
different media, as well as leakage and flash over high-resistance
faults.
