    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 and a corresponding method determin e whether arcing is present in electrical circuits. The assembly powers-up quickly without dissipating excessive heat while power is being supplied to the assembly. The assembly comprises a sensor, a broadband noise circuit, a controller, and a dual-mode power supply. The sensor detects a current flowing in an electrical circuit and develops a corresponding sensor signal. The broadband noise circuit determin es the presence of broadband noise in the sensor signal and produces a correspondin g output signal. The controller processes the sensor signal and the output signal in a predetermined fashion to determine whether an arcing fault is present in the circuit. The dual-mode power supply supplies power to the sensor, broadband noise circuit and controller using a first mode and later switching to a second mode. The first mode reaches steady state faster than the second mode.

    Abstract: An integrated protection system for an electrical distribution system including a panelboard for receiving power from a utility source and distributing the power to a plurality of branch circuits each having line and neutral conductors for delivering the power to a load. The integrated protection system comprises a plurality of arcing-fault detectors and line interrupters attached to positions in the panelboard. The arcing-fault detectors detect the occurrence of an arcing fault in either of the branch circuits, while the line interrupters disconnect the load from the power source in response to the detection of an arcing fault in either of the branch circuits. The line interrupters and arcing-fault detectors may comprise separate modules, each being connected to one of the positions in panelboard or being attached externally to the other module. Alternatively, the line interrupters and arcing-fault detectors may be combined within individual modules, each individual module being connected to a position in the panelboard. An isolation module may be attached to one of the positions in the panelboard for electrically isolating arcing-fault signals to the branch circuit on which they occur.
