摘要： An apparatus and method for detecting arc faults that have reduced susceptibility to nuisance tripping. The apparatus includes a current sensor, an input sense circuit, an arcing sense circuit, a power supply, a tripping (firing) circuit, a processor, and an electromechanical interface. The current sensor monitors a power input comprising an AC current, and provides high frequency components of the. AC current to the input sense circuit. The input sense circuit filters and rectifies the AC signal, and provides the rectified signal to the arcing sense circuit. The arcing sense circuit provides a voltage level accumulated over a predetermined time period, and digital signals indicative of possible electrical arcing occurring during the sampling period, to the processor. The processor measures the voltage level, stores information relating to measured voltages and the digital signals, and processes the stored information using one or more algorithms, thereby determining whether the signals resulted from an arc fault or a nuisance load. In the event the signals resulted from an arc fault, the processor activates the firing circuit to trip the electromechanical interface, thereby interrupting the power output to the load.

摘要： In an embodiment, an apparatus may include a sense element that may measure a property such as, for example, pressure. The sense element may produce an output based on the measured property. Circuitry associated with the sense element may store a voltage that represents the output produced by the sense element. The circuitry may include, for example, a capacitor which may store the voltage. The stored voltage may include one or more parasitic components such as, for example, an offset voltage and/or voltage associated with current leakage. The circuitry may adjust the stored voltage to compensate for the parasitic components. The adjustment may occur over a series of phases of operation of the circuitry.
