1. A method for detecting a series arc in an alternating current electrical system, comprising:
- passing raw current signals from a conductor in the electrical system through one or more filters to provide a filtered signal;
extracting one or more features from said filtered signal; and
classifying said one or more features to a known state of the series arc.

Abstract
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 from a conductor in the electrical system through one or more filters to provide a filtered signal; extracting one or more features from the filtered signal; and classifying the features to a known state representative of the series arc.
