Abstract
Example embodiments of the invention include a powdered core bead body configured to become an inductive impedance to current signals with high frequencies in a power wire threaded through the powdered core bead body. The signals are detectable by a high frequency voltage sensor that is configured to output an arc fault tripping indication to an arc fault tripping circuit in response to an occurrence of high frequency current signals in the power wire.
