Abstract: Low cost apparatus and methods of detecting arc faults for better discriminating electrical events. The arc fault detection apparatus includes a current sensor, a di/dt input sense circuit, a dv/dt input sense circuit, and a processing unit. The current sensor monitors a power line current, and provides high frequency components of the power line current to the di/dt input sense circuit. The dv/dt input sense circuit monitors a power line voltage. The di/dt and dv/dt input sense circuits generate signals carrying information relating to changes in the power line current and the power line voltage, respectively. The processing unit analyzes these changes in the power line current and the power line voltage to discriminate detected electrical arcing events from nuisance loads with increased accuracy.

Abstract: An apparatus and a method of detecting arc faults that have reduced susceptibility to nuisance tripping. The apparatus includes a current sensor, a differential current input sense circuit, a differential current (di/dt) characteristics sense circuit, an absolute current input sense circuit, an absolute current characteristics sense circuit, a power supply, a tripping circuit, a processing unit, and an electromechanical interface. The di/dt characteristics sense circuit provides information relating to the characteristic di/dt signature of a power line current. The absolute current characteristics sense circuit provides information relating to the absolute current waveform characteristics of the power line current. The processing unit correlates the di/dt characteristics to the absolute current characteristics to distinguish between electrical arc faults and nuisance loads, thereby reducing the susceptibility of the apparatus to nuisance tripping.

Abstract: A tester for an arc fault circuit interrupter that can selectively simulate and apply electrical arc faults and nuisance loads to at least one device under test (DUT). The tester includes a power supply, a test controller, and test circuitry coupleable to a DUT. AC power input is provided to the DUT and the power supply, which regulates the AC power input to a DC level for powering the test controller. The test circuitry full wave rectifies AC current returning from the DUT, and the test controller controls a switch in the test circuitry. When the switch is on, the AC current flows through the DUT, the full wave rectifier, the load, and the switch to ground. To simulate an arcing condition, the test controller turns the switch on and off at random intervals. To simulate a nuisance load condition, the test controller turns the switch on and off at periodic intervals. In this way, proper operation of the DUT can be verified under both arcing and nuisance load conditions.

Abstract: A communications circuit can operate with a data channel and a control channel. A changeable portion of the circuit can be reconfigurable between a first mode associated with activity on the control channel only and a second mode associated with activity on both the data channel and the control channel. The first mode can be selected to reduce power consumption compared to the second mode. Controller circuitry is provided to sense signals associated with the control channel and to switch the changeable portion between the first and second modes.
