Study on the influence of identify orientation on acoustic-based fault diagnosis for circuit breakers in switchgear

As key equipment in the power system, the operating state of switchgear circuit breakers directly affects power grid reliability. Traditional fault diagnosis methods suffer from complex installation and high susceptibility to interference, while voiceprint diagnosis has become a research hotspot due to its non-contac...

Circuit breaker sound source localization method based on cross-channel attention fusion

Identifying the active circuit breaker in densely packed distribution cabinets is challenging, as acoustic signatures from neighboring breakers often overlap. At the same time, microphone-array-based localization remains expensive to deploy. To address these limitations, we propose a stereo-enhanced cross-channel atten...
