Patent abstract
In some examples, a device includes at least one input node configured to receive a signal indicating a current through a conductor to a load. The device also includes circuitry configured to determine a first magnitude of the received signal in a first frequency range by applying a first bandpass filter to the received signal. The circuitry is also configured to determine a second magnitude of the received signal in a second frequency range by applying a second bandpass filter to the received signal. The processing circuitry is further configured to determine that an electric arc has occurred on the conductor based on the first magnitude and the second magnitude.
