Working Principle
This device uses the acoustic-magnetic synchronization method to precisely determine the fault point. It is a very accurate and unique point-fixing method. Its
principle is based on the traditional acoustic point-of-sound method with the addition of electromagnetic signal detection and application.
When the high-voltage generator performs impulse discharge on the faulty cable, the sound generated by the discharge at the fault point is transmitted to the ground, and the sound signal is picked up by a high-sensitivity probe. After being amplified, it is monitored with headphones, and the "pop" sound can be heard.
The probe's built-in 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 sound propagation speed. By detecting the time difference between the electromagnetic signal and the sound signal, the distance of the fault point can be judged. Keep moving the position of the sensor to find the point with the smallest acoustic and magnetic time difference, then the exact location of the fault point is below it.
The traditional sound measuring point meter generally only uses headphones to monitor, or supplemented by the movement of the pointer of the meter to distinguish the discharge sound of the fault point. Because the discharge sound is fleeting, and is not much different from environmental noise, it often brings great difficulties to operators who are not very experienced. Acousto-magnetic synchronization method effectively avoids the above problems of traditional acoustic measurement method.
