Summary: | An arcing fault protection assembly in an electrical device, and corresponding methods determine whether arcing is present in the device. The assembly comprises a sensor, a broadband noise circuit, and a controller. The sensor detects a current and develops a corresponding sensor signal. The broadband noise circuit determines the presence of broadband noise in the sensor signal and produces a corresponding output signal. The controller processes the sensor signal and the output signal in a predetermined fashion to determine whether an arcing fault is present. The sensor, broadband noise circuit, and controller are mounted to the device. |
