| Summary: | The present invention relates to the protection of electrical circuits and, more particularly, to the detection of arcing faults in an electrical assembly for mounting on device.
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. |
