ELECTRIC ARC DETECTION |
| 摘要 |
A method for detecting electric arcs in a closed chamber having no openings larger than 5 mm and defining a gas volume to be monitored. The method includes a step of measuring a sound level captured by a microphone, placed inside the chamber, at frequencies greater than about 60 kHz while filtering out the lower frequencies, and a step of comparing the level with a threshold. |

1. A method of detecting electric arcs in a closed chamber, comprising no openings larger than 5 nm, defining a gas volume to be monitored, comprising:
a step of measuring a sound level, captured by a microphone placed inside of the chamber, at frequencies higher than approximately 60 kHz while filtering out the lower frequencies; and a step of comparing said level with a first threshold. |
