Abstract
Systems, methods, and apparatus for corona detection using audio data are provided. In one example embodiment, the method includes obtaining, by one or more computing devices, audio data indicative of audio associated with an electrical system for at least one time interval. The method includes partitioning, by the one or more computing devices, the audio data for the time interval into a plurality of time windows. The method includes determining, by the one or more computing devices, a signal indicative of a presence of corona based at least in part on audio data collected within an identified time window of the plurality of time windows relative to audio data collected for a remainder of the time interval.
Claims17
A method for detecting corona in an electrical system, the method comprising:
- obtaining, by one or more computing devices, audio data during at least one time interval, the time interval including a plurality of time windows;
- partitioning, by the one or more computing devices, the audio data into a plurality of window audio data each corresponding to a respective one of said time windows;
- and
- determining, by the one or more computing devices, a signal indicative of a presence of corona based at least in part on at least one window audio data relative to a remainder audio data wherein said remainder audio data includes interval audio data absent the selected one of the window audio data.
A system for detecting corona in an electrical system, the system comprising:
- a microphone configured to obtain audio data associated with the electrical system;
- a network interface;
- one or more processors;
- and
- one or more memory devices, wherein the one or more memory devices store computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations including:
- obtaining audio data from the microphone, the audio data during at least one time interval, the time interval partitioned into a plurality of time windows;
- partitioning the audio data into a plurality of window audio data each corresponding to a respective one of said time windows;
- determining a signal indicative of a presence of corona based at least in part on at least one window audio data relative to a remainder audio data, wherein said remainder audio data includes interval audio data absent the selected one of the window audio data.
