Abstract

See full text

Arc fault detection devices and methods are described current between a source and a load is periodically measured. A variance of the periodically measured current values is derived and an arc fault can be detected abased on the derived variance. A variance interval signal can be incremented based on the derived variance increasing above a threshold level and a low pass filter arranged to detect an arc based on the incremented variance interval signal.
