  • Patent number: 7349188
    Abstract: An arc fault detector analyzes patterns in a sequence of counts of interval to interval increases or decreases in integrated current for patterns characteristic of arc faults. In AC systems, the interval can be a full cycle or in an alternative embodiment, the changes in integrated current for positive and negative half cycles are separately determined and then interleaved before the change counts are calculated. The count sequence is reset when patterns characteristic of phenomena other than an arc fault are detected to avoid nuisance trips.

  • Publication number: 20040027749
    Abstract: Arcing faults in dc electric power systems are detected by apparatus which responds to a predetermined drop either in voltage across, or current drawn by, a dc load. The voltage and current drops can be measured values or scaled to the source voltage. In another arrangement, the load current is interrupted momentarily when a step decrease in current is detected. If the dc current does not return, within a predetermined margin, to the decreased value before interruption, arcing is indicated. In a third embodiment, drift of the load current following detection of a step decrease, either upward toward a short or downward toward an open circuit, is taken as an indication of arcing.

  • Patent number: 6590757
    Abstract: Electrical equipment (14) is safeguarded from damage due to parallel arc faults by a circuit that provides several levels of protection. A semiconductor switch (18) and a current sensor (24) are placed in series with the electrical equipment (14). When the current to the equipment exceeds a first threshold for a predefined period of time, the semiconductor switch (18) is rendered non-conductive until the circuit is specifically reset. When the current to the equipment exceeds a greater second threshold, a pulsed signal alternately places the semiconductor switch (18) in conductive and non-conductive states so that the average current applied to the equipment (14) is within an acceptable level. The pulses are measured to determine whether a parallel arc fault has occurred. When the measured pulses (74) are within a predetermined range, a parallel arc fault is declared and the semiconductor switch (18) is rendered non-conductive.
