Description
Overview
GAOTek acoustic and magnetic cable fault locator has accurate positioning of the cable fault test has always been a critical step. Even with an accurate rough measurement distance, due to the influence of the external environment, it is difficult for us to quickly and accurately locate it. GAOTek acoustic and magnetic cable fault finding is a portable, ultra-quiet, visualized, and path-indicating impact discharge receiving precise pointing instrument. It is used in conjunction with a high-voltage impact generator and uses the magnetic field signal generated by the impact discharge at the cable fault point. The time difference between the signal and the sound signal is used to pinpoint the exact location of the cable fault point. At the same time, it adopts the leading background intelligent noise reduction and sound tracking technology, which can realize continuous optimization and perfect sound effect. The discharge sound can be measured and heard through the earphone, which can be used to assist in judging the cable. The location of the fault point, the error is within the diameter of the probe. It has the function of indicating the path while accurately determining the point, ensuring fast positioning. When GAOTek uses the continuous impact discharge of the front end, the impact discharge sound of the fault point within the rough measuring distance range propagates on the ground above the cable and is recorded by the ground penetrating sensor on the ground. The distance between the detection point and the real fault point of the cable can be calculated by two methods, one is the volume of the impact discharge noise; the other is the time difference between the magnetic field signal and the sound signal sent out synchronously at the moment of discharge at the fault point to reach the ground penetrating sensor.
