Abstract

To guarantee save and reliable operation of low voltage grid devices and to protect all devices from disturbance or damage, it is absolutely necessary to separate normal operation from fault state. A typical fault state with an enormous hazard potential is the arc fault. Due to the high level of energy involved, it can lead to the total write-off of affected devices and hence interrupt the energy supply (service). To prevent extensive consequences, there is a high demand to detect these error conditions and to terminate the fault state in a period of a few milliseconds. The analysis of typical electrical and non-electrical signals with numerical algorithms enables fast detection of arc faults.
