This device uses the acoustic-magnetic synchronization method to
accurately determine the fault location. It is a very accurate and
unique location method. Its principle is based on the traditional
acoustic point determination method and adds the detection and
application of electromagnetic signals.
When the high-voltage generator performs impact discharge on the
faulty cable , the sound generated by the discharge at the fault
point is transmitted to the ground. The sound signal is picked up
by a highly sensitive probe . After amplification, a "pop" sound
can be heard by listening with headphones.
The built-in probe of the probe receives the magnetic field signal
in real time, and uses the principle that the propagation speed of
the magnetic field is much higher than the propagation speed of
sound to determine the distance of the fault point by detecting the
time difference between the electromagnetic signal and the sound
signal. Keep moving the sensor position to find the point with the
smallest acoustic-magnetic time difference, then the exact location
of the fault point will be below it.
Traditional acoustic measurement legal point instruments generally
only use earphones to monitor, or are supplemented by the swing of
the meter pointer to identify the discharge sound at the fault
point. Since the discharge sound disappears in an instant and is
not much different from the ambient noise, it often brings great
difficulties to operators who are not very experienced. The
acoustic-magnetic synchronization method effectively avoids the
above problems of the traditional acoustic measurement method.

Composition of the instrument
1. Cable fault locator: accurately locate cable fault points within
the rough measurement range.
2. Probe: including probe, probe, connecting rod , and three claws , which are connected to the input channel to receive signals.
3. Wear headphones; connect the input channel of the pointing
instrument (feedback of the output signal).
4. 7-core signal cable: connecting cable between the pointing
instrument and the probe (connecting the pointing instrument and
the probe).
5. Charger: Connect to the charging socket of the instrument for
charging.
6. Multifunctional flower wrench: used for disassembling and
assembling connecting rods.
