DISPOSITIF ET PROCEDE POUR DETECTER L'AMORCAGE D'UN ARC ELECTRIQUE

摘要

An apparatus and method for detecting an arc fault using a power conductor (14) on a printed circuit board (PCB) (10), which supplies power from an external power source to electrical components on the PCB (10) by sensing a value indicative of the rate of change of current passing through the power conductor (14). The apparatus and method may be used for detecting arc faults both internal and external to the PCB (10).
