This disclosure relates to a method and apparatuses for detecting and reporting suspected tampering of an energy meter to a utility. The method and apparatus uses a plurality of sensors to obtain data relating to one or more input parameters based on the type of input signal. The input parameters are mapped with a tamper type to provide a classification of one or more output parameters. The output parameters are compared to one or more operating conditions of the energy meter to identify one or more suspected tampers. Any suspected tampers are reported to the utility.

When securing a watthour meter to a meter box base, a meter sealing ring is typically used. A quick-fastening watthour meter retaining member is provided, in certain embodiment of the present invention, to reduce installation time and generally comprises a circular band, a connector housing member, and a receiver housing member. The connector housing member and a receiver housing member are preferably mounted to the terminus ends of the circular band. A portion of the connector housing member, comprising locking protrusions or “teeth”, is adapted to engage, with a ratchet-type action, in one example embodiment, and fasten into the receiver housing member, which contains, a pre-installed “padlock type” frangible sealing device in an example embodiment. Removal of the ring is accomplished by simply cutting, in one embodiment, and removing the frangible sealing device and allowing the housings to disengage from each other.

An electricity meter comprising an electrically-controlled electromechanical switch is disclosed. The electromechanical switch comprises a rotary actuator comprising a generally-cylindrical permanent magnet rotor having a central axis, a stator comprising a closed stator core and first and second opposite stator poles inwardly-projecting from the closed stator core towards the rotor and first and second coils wound around the first and second stator poles respectively. The electromechanical switch comprises a switch comprising at least one pair of first and second contacts wherein the first contact is movable. The electromechanical switch comprises mechanical linkage between the rotary actuator and the movable contact(s) configured such that rotation of the rotor from a first angular position to a second angular position causes the switch to be opened, and rotation from the second angular position to the first angular position causes the switch to be closed.

An anti-tamper device for a utility meter, in particular for an enclosure thereof, providing a guideway for a sealing element, wherein in a sealed state of the utility meter, at least a section of the sealing element extends along the guideway. Furthermore, an enclosure for a utility meter comprising a socket configured for receiving an anti-tamper device, as well as a utility meter comprising an anti-tamper device, and/or an enclosure. The guideway is provided with a predetermined breaking zone configured to break when the sealing element exerts a predefined breaking force onto the anti-tamper device.

An abnormal electricity use method is disclosed. An embodiment includes: classifying a transformer into a public transformer or a dedicated transformer, the public transformer corresponding to a plurality of first users; the dedicated transformer corresponding to one second user; recognizing a first abnormal user from the first users based upon the smart meter reading of the public transformer and the smart meter reading of the first user; or recognizing the first abnormal user from the first users based upon the smart meter reading of the first user; and recognizing a second abnormal user from the second user based upon the smart meter reading of the second user or the smart meter reading of the dedicated transformer. Respective personalized anomaly recognition policies are used for the public transformer having a plurality of first users and the dedicated transformer having only one second user, to improve the recognition accuracy and speed.
