Abstract
A method and apparatus that monitors and controls an operation of an electricity meter. A potential failure condition of an electrical connection between an electricity meter and a meter socket in an electrical line that provides power from a power supply to an electrical load through the electricity meter, is detected. A correction time may be determined based on a temperature in a vicinity of and a current through the electrical connection, and may indicate an amount of time before a predicted failure of the electrical connection will occur. The method determines whether the electricity meter is in an imminent failure condition based on the correction time or the information used to detect the potential failure condition of the electrical connection. The method may provide either, or both, notification of the imminent failure condition and disconnection of power to the electrical load by operating a disconnection switch.
