摘要： An arc fault circuit interrupter includes a line terminal, a load terminal, separable contacts electrically connected between the line terminal and the load terminal, and a current sensor structured to sense current associated with the load and flowing between the line terminal and the load terminal and through the separable contacts. The sensed current includes a plurality of line cycles. An arc fault detection circuit is structured to provide series arc protection and to generate a trip signal responsive to the sensed current from the current sensor. The arc fault detection circuit collects a plurality of samples of the sensed current over the line cycles, determines a single current transient associated with energization of the load, and responsively inhibits the series arc protection. An operating mechanism is structured to open the separable contacts responsive to the trip signal.

摘要： An arc fault circuit interrupter includes line and load terminals, separable contacts in series between the terminals, a neutral conductor, and an operating mechanism opening and closing the contacts and tripping open the contacts in response to a trip signal. A current transformer senses current flowing through the contacts. A voltage sensor detects voltage zero crossings between the load terminal and the neutral conductor. A processor detects a resistive series arc in series with the contacts. A processor routine determines, for each half cycle, samples of the sensed current, an offset value from an average of sensed current samples proximate the voltage zero crossings for the corresponding half cycle, adjusted sensed current samples as adjusted by the offset value, a profile corresponding to a resistive series arc as a function of the sensed current samples and the adjusted samples, and the trip signal in response to occurrences of the profile.

摘要： An arc fault circuit interrupter includes separable contacts, an operating mechanism, a current sensor sensing current flowing through the contacts and outputting a sensed current, and a processor determining and storing peak values of the sensed current for plural half-cycles. The processor provides arc fault detection, determines whether a first predetermined plurality of half-cycles occur in succession and correspond to non-unity power factor, and responsively inhibits the detection for a first predetermined time, and whether a second predetermined plurality of half-cycles occur in succession, each with smaller peak amplitude than that of an immediately preceding half-cycle of like or differing polarity, and responsively inhibits the detection for a second predetermined time. The processor determines that the detection is not inhibited for the first and second predetermined times, and responsively indicates that any of the half-cycles having a peak amplitude greater than a predetermined amount is a parallel arc.
