Product Description
XHDD503C cable fault pinpointer
It adopts the acoustic-magnetic synchronization method to pinpoint the fault, which is a very accurate and unique pinpointing method. When the high-voltage generator shocks and discharges the faulty cable, the sound produced by the discharge at the fault point is transmitted to the ground, and the sound signal is picked up by the high-sensitivity probe. After being amplified and monitored by earphones, you can hear the "pop" sound.
At the same time, the built-in probe of the probe receives the magnetic field signal in real time, using the principle that the propagation speed of the magnetic field is much higher than the speed of sound propagation, and judges the distance of the fault point by detecting the time difference between the electromagnetic signal and the sound signal. Move the sensor position continuously to find the point with the smallest time difference between the acoustic-magnetic and the magnetic field, then the accurate position of the fault point is below it.
Product Features:
1. The acoustic detection method is combined with the acoustic-magnetic synchronization method, and the operator can freely choose the detection method according to the usage habits.
2. When the acoustic-magnetic synchronization method is used for positioning, the equipment automatically and quickly calculates the acoustic-magnetic field time difference and displays the difference. The operator can quickly and accurately find the fault point according to the difference, thereby improving the detection efficiency.
3. The equipment is designed with background noise reduction technology. When the acoustic detection method is used to detect the fault point, as long as the operator presses the BNR key, the environmental interference noise can be effectively filtered out and the discharge sound of the fault point can be clearly heard.
4. The gain value and trigger value of the acoustic signal and magnetic signal can be manually adjusted according to the actual situation of the detection site to make the detection more accurate.
5. The equipment has a cable path auxiliary indication function to prevent the operator from deviating from the cable path when positioning.
6.7-inch touchable high-brightness LCD color screen, which can be clearly displayed regardless of day or night.
7. Built-in rechargeable lithium-ion battery, fast charging and long use time.
8. Small size, light weight, easy to carry.
