(57)< Abstract > Especially, for electrical energy distribution low the device which prevents the arc which becomes fault for the voltage breech operating mechanism, that, consists of with the arc detector which at least becomes one which it activates controls the opening and closing component ...

An arc fault circuit interrupter which protects an AC circuit subjected to a possible arcing fault includes a sensor which produces a signal that can be evaluated to see if it is associated with arc fault current. The evaluation is done by a discrimination circuit which identifies a ...

Arc fault detection method and apparatus employ an impedance-based current sensor to provide a sensing signal indicative of current through a conductor. The impedance-based current sensor diverts high frequency components of current through the conductor and converts the high frequency components into ...

and c) from the difference of the two time points (t1 and t2) each determined a time interval (t1t2), each an arc fault is detected when the amount of the time interval (Bt1t2) below a vorge time value (ZW), and that then tripping occurs to limit the energy of the arc fault....
