  • Systems, methods, and devices for controlling a serial arc fault in an electrical circuit
    Patent number: 7872839
    Abstract: Methods, systems, and devices for controlling a serial arc fault in an electrical circuit are disclosed. In some embodiments, the methods include the following: a. measuring a current in the circuit; b. determining whether the current is below a predetermined value; c. if the current is below ten percent of the predetermined value, determining whether a countdown timer value indicated by a cell pointer value is equal to zero; d. if the countdown timer value is equal to zero, starting a countdown timer, advancing the cell pointer value by one, and restarting the method at step a.; e. if the countdown timer value is not equal to zero, determining whether the interruptions in the current are periodic; f. if the interruptions in the current are not periodic, checking whether an arc event countdown timer is running; and g. if the arc event countdown timer is running, tripping a circuit breaker.
