1. 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;
determining, by the one or more computing devices, a scaled ratio for each one of the plurality of time windows based on the plurality of window audio data; 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 scaled ratio of the scaled ratios.
