An electrical arc detector for a series electrical connection as may be associated with an electric meter may comprise: an arc detector housing; a source of electrical power; a de-tuned resonant tank circuit configured to receive a magnetic field and/or an electric field generated by an electrical arc at a series electrical connection; an electrical detector for detecting signals generated in the de-tuned resonant tank circuit responsive to the magnetic field and/or the electric field generated by an electrical arc; and an output device responsive to the electrical detector and configured to provide a human perceivable indication of detection of an electrical arc at the series electrical connection.
