An electronic flashover is generated by means of an impingement discharge generator. The acoustic and magnetic signals of the electronic flashover wave are picked up and amplified by the corresponding probes, and are judged by hearing and visual. To determine the exact location of the fault point, that is, to complete the precise positioningtask within the rough measurement range of the cable fault point. Performance: (1) Acoustic waves and electromagnetic waves generated when the fault point is discharged can be synchronously received to determine the position of the cable fault point. (5) Receive signal: vibration and magnetic field signals when the fault is discharged Usage: Cable path meter is a special instrument for accurately detecting the position and depth of buried cable in a certain range; path detection is completed by the path signal generator and path signal receiver (cable fault fixed point meter); The cooperation between the two uses the operation to accurately locate the cable path within the approximate cable embedding range.Main composition Path detection is mainly composed of path signal generator and receiver index parameter a) big power output, anti-vibration, strong anti-interference ability, stable and reliable; b) With reliable over current, open circuit and short circuit protection function; c) Output Frequency: Audio Frequency. d) Output signal: intermittent, 0~50Vpp e) Working power supply: AC 220V±10%,50/60Hz; 4 High voltage generator HZ-535-4 The device integrates a DC high-voltage source, a storage capacitor,a discharge ball device, an automatic discharge device, and a cable fault tester into a cart-type high-end experimental instrument.
