Wind-resistant fault location method for aerial cables using speaker-assisted distributed vibration sensing

We propose a method for aerial cable position identification that combines distributed vibration sensing (DVS) with acoustic excitation. By employing targeted vibrations transmitted through direct contact between a speaker and the cable and utilizing frequency-selective detection, this approach effectively mitigates wind-induced noise. Field trials demonstrated successful position identification even under windy conditions, highlighting the method’s potential to significantly enhance the efficiency and reliability of network maintenance operations.
