More Information
Summary:An autonomous adaptive arc fault detection device includes a memory for storing data of arc fault tripping events detected on a circuit over a period of time. The device also includes a processor, in communication with the memory, for determining whether a newly detected arc fault tripping event is an unwanted tripping event based on a number of times a same type of tripping event, as the newly detected arc fault tripping event, has occurred, and inhibiting interruption of the circuit if the newly detected arc fault tripping event is determined to be an unwanted tripping event. The memory can store data, such as sensed or calculated electrical characteristic parameters defining a signature of a detected arc fault tripping event as well as a number of times a stored tripping event has occurred over a period of time.
