Methods and systems for detecting series arcs in electrical systems
A method of detecting a series arc in an alternating current electrical system is provided. The method is a pattern-recognition based approach and includes passing raw current signals ( y 1 ) from a conductor in the electrical system through one or more filters (22) to provide a filtered signal ( y...

| Zusammenfassung: | A method of detecting a series arc in an alternating current electrical system is provided. The method is a pattern-recognition based approach and includes passing raw current signals ( y 1 ) from a conductor in the electrical system through one or more filters (22) to provide a filtered signal ( y 2 ); extracting one or more features ( y 3 , y 4 , y 5 ) from the filtered signal ( y 2 ); and classifying the features to a known state representative of the series arc. |
