BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Conventional energy meters include a controller, a display, batteries, switches, sensors, memory and measuring elements. Meter pulses are proportional to the energy accumulated in the register. Each pulse represents a pre-determined quantum of energy consumed by a load connected with the energy meter. The data is stored in the register memory for display and/or transmission. The data can include voltage, current, power factor, frequency, instantaneous power, energy, monthly consumption, weekly consumption, daily consumption, load profile etc. These parameters give the functionality of the meters and its sensors.
[0004] However, the energy meter is subjected to various failures in terms of drift in performance of its components, abnormalities in functionality. These abnormalities are preferably to be identified prior to their occurrence or in early stages of occurrence in order that appropriate warnings and alerts may be issued.
[0005] There is, therefore, a requirement in the art for a means to monitor health of an energy meter and determine occurrence of failure.
[0006] All publications herein are incorporated by reference to the same extent as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
