摘要
An electric meter contact arc detector is mountable to an electric meter base and may comprise: a de-tuned resonant tank circuit configured to receive a magnetic field and/or an electric field from an electrical arc at a stab contact; an electrical detector detecting signals generated in the de-tuned resonant tank circuit responsive to the electrical arc at the stab contact; and an output device indicating detection of an electrical arc. A disconnect device responsive to the electrical detector and configured to interrupt an electrical connection to the stab contact, may be provided. An electrical arc at the stab contact may thus be detected and may cause an electrical connection to the stab contact to be interrupted.
