Electrical arc detection methods and apparatus |
| abstract |
In at least one embodiment, the inventive technology may involve arc detection methods and apparatus for use in photovoltaic power systems. One general aspect may involve the determination of lower noise regions of a fourier transformation of a parameter (e.g., voltage, current or power) signal measurement at a location in the system, and a comparison of fourier transformed signal values at such locations at different times to assess atypical increases in value and thus possible arcing. Polling protocols may be used to further reduce false positives. Certain other aspects may relate to comparison of synchronized voltage measurements to assess presence of arc condition. Any aspect may involve automatic, positive arc condition response circuitry that acts to automatically mitigate undesired effects of an arc in the event of arc detection. |
