ARC FAULT PROTECTED DEVICE

摘要

An arcing fault protection assembly in an electrical device, and correspondi ng 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 determin es the presence of broadband noise in the sensor signal and produces a correspondin g output signal. The control]er 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.
