Embodiment Construction

[0017] According to one aspect of the present invention, there is provided a system including a meter (electric meter or other power measuring device), and a method for monitoring and controlling the operation of the meter to prevent failure of the meter and / or damage to the meter. The method is applied to the electrical connection of a meter in a power line that provides power from a power source to a load through the meter. The method includes detecting at least one potential fault condition of the electrical connection, and determining a correction time based on the detected at least one potential fault condition. The correction time estimates the total time before a predicted failure of the electrical connection will occur. The method includes determining whether the meter is in an imminent failure condition based on one of the detected at least one potential failure condition of the electrical connection and a time to correct. The method further includes disconnecting po...

Abstract

A method and apparatus for monitoring and controlling the operation of an electricity meter and preventing failure of the electricity meter and / or damage to the electricity meter. Detection of potential fault conditions on the electrical connection between the meter and the meter receptacle in the electrical route that supplies power from the source to the electrical load through the meter. Correction times may be determined based on the temperature in the vicinity of the electrical connection and the current flow through the electrical connection. Correction time represents the amount of time available 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 information used to detect a potential failure condition of the electrical connection.

Description

technical field [0001] The present invention relates to methods and apparatus for preventing failure of electricity meters due at least to the deterioration of the electrical connection of the electricity meter socket between the power source and the load. Background technique [0002] A conventional electricity meter includes an electrical connection between a power source and a load. Deterioration of the electrical connections, for example including deterioration of the meter socket, can create a high temperature heat source inside the meter. Although an alert can be sent to the utility company, conventional meters continue to operate when such meters are exposed to excessive heat. Continued operation under these conditions can cause meter failure. Contents of the invention [0003] Accordingly, it is an object of the methods and apparatus described herein to monitor and control the operation of the electricity meter and preventively disconnect power to the load before...
