Fast Numerical Algorithms for Arc Fault Detection

In (European) low-voltage networks, short circuits usually result in high current arc faults. These need to be cleared in a very short time since arcs cause large damages to adjacent equipment and present persons, mainly due to their high temperatures. Today, optical systems are used to ensure fast detection of arcing faults. In this paper, novel methods will be proposed for arc fault detection based on the measurement of current and voltage. Compared to optical systems, the proposed method shows a high performance.
