    Abstract: In order to determine whether arcing is present in an electrical circuit, a sensor signal (didt) , corresponding to current in said electrical circuit is processed. The sensor signal is filtered (50,52,54) , to determine the presence of noise in a predetermined frequency range and produce a corresponding filtered signal. The corresponding filtered signal is compared (60) , to a reference threshold voltage to generate an output signal potentially indicative of arcing. A selection (61) , is made of one from a plurality of available threshold voltages as the reference threshold voltage for use in the comparing operation. The detection operation supports either or both branch feeder arc fault detection and/or series arc fault detection.

    Abstract: A system for testing an arcing fault detection system in an electrical distribution network having a line conductor carrying an electrical signal between a power source and a load, the arcing fault detection system including a sensor coupled to the line conductor for monitoring the electrical signal and generating a sensor signal representing the electrical signal, the arcing fault detection system generating and arc-indicative signal in response to the sensor signal having characteristics indicative of an arcing fault. The testing system couples the sensor to a test line simultaneously with the line conductor and periodically produces a test signal on the test line. The sensor simultaneously monitors the test signal and the electrical signal and produces a sensor signal representing both the test signal and the electrical signal when the test signal is present on the test line. The arcing fault detection system generates an arc-indicative signal in response to the sensor signal associated with either the test line or line conductor having characteristics indicative of an arcing fault. A diagnostic test integrator evaluates the status conditions of the test signal and the arc-indicative signal and generates a trip signal to trigger the interruption of the electrical signal in response to certain status conditions of the test signal and the arc-indicative signal.

    Abstract: An arcing fault protection assembly in an electrical outlet, and a corresponding method determine whether arcing is present in an electrical device connected to the outlet. The assembly comprises a sensor, a broadband noise circuit, a controller and an electrical device. The sensor detects a current and develops a corresponding sensor signal. The broadband noise circuit determines the presence of broadband noi se in the sensor signal and produces a corresponding output signal. The controller processes the sensor signal and the output signal in a predetermined fashion to determine whether an arcing fault is present. The sensor, the broadband noise circuit and the controller are mounted to the outlet receptacle or to an outlet box which houses the receptacle. The electrical device is connected in parallel to the first electrical outlet on the load side of the sensor.

    Abstract: Method and apparatus for testing the operation of an arcing fault circuit interrupter by introducing a simulated fault signal to a branch circuit and watching an indicator for the successful operation or failure of the circuit breaker. The simulated faults may be line to neutral or line to earth arcing faults. The simulated fault may comprise a high (di/dt) rate of change of current between line and neutral. The simulated faults may be separately selectable 70,72. The apparatus may comprise a small hand held housing 5 and may comprise a plug unit 30 with connectors 32 for mating with an AC receptacle socket 33. The indicator may be a LED28. Circuitry is also shown in figures 1a, 1b.

    Abstract: An arc fault detector system (10) detects arcing faults in an electrical distribution system by monitoring one or more conductors (14) and producing an input signal representing one or more electrical signal conditions in the circuit (12) to be monitored. This input signal is processed to develop signals representing the electrical current flow through the monitored circu it (12) and broadband noise signal components. The system (10) analyzes these signals to determine whether an arcing fault is present, and if so, outputs a trip signal which may be used directly or indirectly to trip a circuit break er or other circuit interruption device (44).
