Cable fault acoustic magnetic fixed point instrument technical indicators:
I. Product overview
HP-C10A cable fault acoustic magnetic precise point meter is a portable, silent, visual impact discharge receiving accurate point meter, is specially used with high voltage impact generator, it uses the leading background intelligent noise reduction and sound tracking technology, can achieve continuous optimization of sound effects, record the impact discharge characteristic sound and the scene will be picked up to achieve the comparison of signals.
When the HP-C10A uses the front-end continuous shock discharge, the sound of the shock discharge at the fault point within the distance of the coarse side propagates on the ground above the cable and is recorded by the ground sensor. The distance between the detection point and the real fault point of the cable can be obtained by the method of shock discharge noise volume.
