Abstract
A method and apparatus for detecting a tamper event in an electrical power metering apparatus having power distribution and power service conductors connected to jaw contacts in a socket housing, the jaw contacts receiving blade terminals of an electrical service meter apparatus. A tamper event signature is detected based on a time relationship between separation of the ground circuit between the electrical power metering apparatus and the socket and the separation of at least one of the power distribution and power service blade terminals from the socket jaw contacts due to removal of the electrical service apparatus from the socket.
