摘要： A tamper detection system for an electricity meter includes an antenna, an RF signal level circuit, and a controller. The antenna is configured to receive an RF signal. The RF signal level circuit is supported within an electricity meter housing and is operatively connected to the antenna. The RF signal level circuit is configured to detect the RF signal received by the antenna and to provide a strength signal corresponding to a magnitude of the RF signal. The controller is supported within the electricity meter housing, and is operatively connected to the RF signal level circuit. The controller is configured to generate an RF signal strength value based at least in part on the strength signal, and to generate a tamper flag responsive at least in part to a determination that the RF signal strength value exceeds a threshold value.

摘要： A method of detecting a magnetic coupling in a meter includes obtaining in an electricity meter information representative of power consumption as measured within the meter of a plurality of lines of an electrical service. The method also includes obtaining from a magnetic sensor information representative of a magnetic field within an electricity meter. A processing circuit then determines whether a first condition exists wherein the magnetic field exceeds a first threshold and the information representative of the power consumption indicates a load imbalance on the plurality of lines such that the load imbalance exceeds an imbalance threshold. The method further includes performing a processing step responsive to a determination that the first condition exists.
