While some of these techniques are more or less effective than others, they require relatively sophisticated arc sensors and circuits. Heretofore, most arc detection circuits have been incorporated in circuit b
There is a need for simple economical arc fault detectors that can be included in wiring devices such as duplex receptacles, multi-outlet strips, or in-line devices, and that offer the same protection as an arc fault detector incorporated in a circuit breaker but at lower cost. There is a...
both of the resonant circuits resonate and cause a Q rise in voltage across each winding102and100. Because the circuits are series connected, the voltages add, thereby producing a large signal across output112. This voltage rise can be large enough to negate the need for a signal amplifier. ...
