摘要： 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 a series connected inductor on each of multiple conductors of a power distribution network for phase/neutral or multi-phase arc detection.

摘要： Methods and techniques are disclosed for an intelligent GFCI device (IGFCI) having a microcontroller programmed to perform self-testing on a periodic basis and communicate the results of this testing to a remote monitoring device such as a remote central logging computer. In some implementations, with two-way (bidirectional) communication, a plurality of self-testing IGFCI devices can be tested and reset systematically from a remotely located device to reduce disruption to users. The IGFCI device can be configured to be automatically reset or manually reset upon the application of AC power to the device.

摘要： 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. The SINE signal generated in combination with a CURRENT input is used to produce a control waveform “DELTA”. DELTA can be represented as a relative value or as an absolute difference between the SINE and the CURRENT. Each occurring half cycle of the DELTA signal is analyzed by, for example, a micro- controller for specific identifiable characteristics found to indicate the presence of arcing. Upon the detection of arcing, an output signal can be generated to activate a circuit interrupting mechanism, sound an audio alarm and/or alert a central monitoring station.

摘要： An electric cable which can be used with a shock hazard protector to provide arc fault and ground fault protection at a minimum cost. The electric cable includes a first insulated conductor for coupling to a phase terminal of a protector, a second insulated conductor for coupling to a neutral terminal of the protector, and a third insulated conductor for coupling to a ground terminal. A separate or common conductive wrap surrounds the first and second insulated conductors but not the third conductor. The conductive wrap is for coupling to a sense terminal of the protector. The cable assures that a fault to ground, such as the energizing of the ground conductor, cannot occur before the fault energizes the conductive wrap. The cross-sectional shape of the electric cable can be substantially flat, substantially round or other shape.

摘要： A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly, eliminating annoying buzzing noises that would otherwise be generated by the motor's windings. The invention provides for motor speed control with infinitely variable speed control settings. Rather than use triacs that generate RFI noise and cause motor windings to buzz due to their inherent avalanche switching, the invention utilizes power FETs or IGBTs to provide the switching function to control power delivery to the motor load . The power switches are controlled by an oscillator that generates a pulse train with a duty cycle controllable by the user. A filter shapes this signal into a trapezoidal control signal that drives the gate input of the power FET or IGBT switch. A kick start circuit turns the motor on initially for two to three seconds to overcome the inertia of the motor and its load. A zero crossing detector prevents the motor from being turned on except at a zero crossing of the AC source to further reduce noise.
