Acoustic Pinpointing is a fault location method that identifies the exact position of a cable defect by detecting the sound wave produced by a spark discharge. When a high-voltage impulse is applied to a damaged power cable, a spark occurs at the fault point. This spark generates a sharp acoustic wave that travels through the ground.
A sensitive acoustic receiver, captures this sound, converting it into an electrical signal. By moving the sensor along the cable route and monitoring where the sound intensity is strongest, the technician can precisely locate the fault site.
This technique is especially effective when used alongside surge voltage generators like the Surge Voltage Generator HVC-G , offering a reliable and non-destructive approach to fault pinpointing—even in complex underground networks.
