| 20080239598 | Arc Flash Elimination Apparatus and Method - An arc crowbar with electrodes separated by a gap in a protective case. Each electrode is connected to an electrically different conductor of a circuit. A sensor detects an arc flash condition on the circuit and signals a trigger circuit to send an electrical pulse to an arc-triggering device in the arc crowbar gap. The triggering device ionizes a portion of the gas between the electrodes, initiating a protective arc between the electrodes that absorbs energy from the power circuit and trips a breaker, eliminating the arc flash condition. The triggering device may be a plasma gun, especially one that injects plasma of an ablated material into the gap. The sensor may signal a circuit breaker to open in the power circuit. Arc flash sensor types may include a differential current sensor and/or an optical sensor. | 10-02-2008 |

| 20080253040 | Ablative Plasma Gun - A plasma gun with two gap electrodes on opposite ends of a chamber of ablative material such as an ablative polymer. The gun ejects an ablative plasma at supersonic speed. A divergent nozzle spreads the plasma jet to fill a gap between electrodes of a main arc device, such as an arc crowbar or a high voltage power switch. The plasma triggers the main arc device by lowering the impedance of the main arc gap via the ablative plasma to provide a conductive path between the main electrodes. This provides faster triggering and requires less trigger energy than previous arc triggers. It also provides a more conductive initial main arc than previously possible. The initial properties of the main arc are controllable by the plasma properties, which are in turn controllable by design parameters of the ablative plasma gun. | 10-16-2008 |
