ABSTRACT:
An electronic meter tamper detection system and method for sensing the removal of an electricity meter from a meter socket and generating a tamper signal when such removal is detected. The tamper detection circuit includes a control unit having an energy storage device that is charged during normal operation of the electricity meter. When power is interrupted to the electricity meter, the control unit applies a charging voltage to a voltage regulating device within the electricity meter. The voltage regulating device can be charged only when the electricity meter is installed within the meter socket. After applying the charging voltage to the voltage regulating device, the control unit senses whether the voltage regulating device has been charged. If the voltage regulating device has not been charged, the control unit indicates that the meter has been removed from the meter socket.
