An experimental proof of concept of time‐reversal single‐sensor acoustic source localisation: Application to partial discharges

open access: yesHigh Voltage, Volume 10, Issue 2, Page 351-361, April 2025.
Abstract In this paper, for the first time, an experimental proof of concept for utilising time reversal (TR) in the acoustic regime to localise partial discharge (PD) sources was presented using a single sensor. To achieve this, an experimental setup comprising a water tank, acoustic transducers for signal transmission and reception, and 2D scanners ...
