International Classification:

H02H 300

US Classification:

361 42, 361 45, 361 78, 361 936, 361 94

Abstract:

An arc fault detector, as a stand alone device or in combination with a circuit interrupting device such as a ground fault circuit interrupter (GFCI), protects from potentially dangerous arc fault conditions. The device utilizes line side and load side pickup coils to distinguish between arc faults occurring on the line or load side. An arc fault circuit interrupter (AFCI) circuitry portion of the device shares components from the GFCI circuitry portion, and utilizes the electromechanical power carrying portion of the GFCI, including AC line disconnect circuitry and a power supply. The AFCI employs quantitative detection using variable gain control in combination with either a load disconnect or audible/visual alarm indication. The device also includes a timer circuit, which permits the user to temporarily inhibit or disable the arc detection, and selective frequency filtering permitting arc detection in the presence of power line carrier communications.

International Classification:

H02H 908

US Classification:

361 42, 324520, 324525

Abstract:

An arc fault detector comprised as a stand alone unit and in combination with a ground fault circuit interrupter (GFCI) functions to provide protection from potentially dangerous arc fault conditions. When combined with a GFCI, the combination arc fault/ground fault circuit interrupter (AFCI/GFCI) provides protection from both arc fault and ground fault conditions. A single transformer is used to detect faults between neutral and ground and arc faults. An impedance splits the current flow into two portions so as to generate differential current proportional to the current flowing through the conductors. An early arcing detector periodically tests the AC line for high impedance between the device and a main breaker panel. The AFCI/GFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal.

International Classification:

H02H 300

US Classification:

361 42, 361 50, 361 45, 361 931

Abstract:

A device for providing ground fault protection for one or more loads in an electrical wiring system. The device includes a pickup for sensing electrical characteristics associated with conductors supplying power to the one or more loads and generating a pick up signal when predefined electrical characteristics are sensed; a ground fault detector powered using conductors that are independent of the conductors supplying power to the one or more loads, said ground fault detector being configured to receive said pickup signal, detect ground faults from said pickup signal, and generate a trigger signal when a ground fault is detected, and a power disconnect responsive to said trigger signal such that when said trigger signal is generated power to the one or more loads is disconnected. A corresponding method is also provided.

US Classification:

335 18, 361 42

Abstract:

Resettable circuit interrupting devices, such as GFCI devices that include a reset lockout mechanism, are provided. The reset lockout comprises a member coupled to swing from a pivot which moves with a reset button to permit the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open condition exists.

Assignee:

Leviton Manufacturing Co., Inc. - Little Neck NY

International Classification:

G01R031/14

US Classification:

324509, 324536

Abstract:

An arc fault detector, as a stand alone device or in combination with a circuit interrupting device such as a ground fault interrupter (GFCI), protects from potentially dangerous arc fault conditions. The device utilizes a line side or load side series connected inductance having an air or magnetic core to generate the derivative di/dt signal of the arc current in the conductor. The derivative signal is fed to an arc fault detector where it is analyzed for the presence of arcing. The device can have two series connected inductors inductively coupled to each other such that the signal from one inductor is inductively coupled into the other inductor for coupling to the arc fault detector.

Assignee:

Leviton Manufacturing Co., Inc. - Little Neck NY

International Classification:

G01R 31/00

US Classification:

702185, 702 59, 361 5, 324536

Abstract:

There is here disclosed a method and apparatus for detecting the occurrence of arcing of a conductor by monitoring the current on an AC power line. The signal detected is split and directed along four separate paths to generate four signals having separate characteristics which represent the current in the line. A first path is for a signal representative of the current flowing in the line. A second path is for a signal having a pulse for each occurrence of a positive step change in current that is significant and has a di/dt value above a predetermined value. A third path is for a signal having a pulse for each occurrence of a negative step change in current that is significant and has a di/dt value above a predetermined value. A fourth path is for a signal having a voltage level representative of the broadband noise signal on the line. Using at least one of five different methods in combination with one of three input signals, a reference signal designated as “SINE” is generated.
