    摘要: Downstream series and parallel arcing in AC power lines is determined by using a detector and microprocessor to detect characteristic di/dt behavior received from a current sensor through which the power lines pass. When downstream parallel arcing is detected, the microprocessor uses a speedy algorithm which cannot be used to detect series arcing. Upstream series arcing is detected by sensing a flat voltage portion of the line voltage. Upstream parallel arcing is detected by sensing a voltage spike followed by a voltage flat portion of the line voltage. When upstream parallel arcing is detected, the microprocessor is temporarily shut off to avoid false tripping.

A circuit interrupter includes four sets of movable contacts configured to be driven into a reset state in response to a reset stimulus, the four sets of movable contacts being configured to be driven into a tripped state in response to the actuation force. A self-test circuit is coupled to the plurality of line terminals or the at least one sensor. The self-test circuit is configured to automatically generate a test signal from time to time during a predetermined portion of an AC power line cycle. The self-test circuit is configured such that the test signal is sensed by the at least one sensor when the at least one sensor is operational, the sensor output signal being a function of the test signal. A monitor circuit is configured to monitor the fault detection circuit or the actuator assembly; the mechanical actuation force is substantially inhibited when the fault detection circuit or at least a portion of the actuator assembly properly respond to the test signal. The monitor circuit generates an end-of-life response if the fault detection circuit or the actuator assembly do not respond to the test signal within a predetermined period of time.
