Analysis of Abnormal Measurement of Smart Meter

Abstract

It is convenient for residents, industry and commerce with the extension of smart meters and the popularization rate of smart meter has reached 100%. However, it exposes many problems of smart meter in field application, such as display fault, communication failure, error out of tolerance, abnormal measurement data, clock abnormal. This paper just analyzes the problem of abnormal measurement data, the result shows that the reasons of the problem contain battery undervoltage, component failure and power failure, they cause the problem of abnormal measurement together. To avoid this problem in the future, it needs higher requirements of the hardware and software reliability, and the replaceable battery is necessary for smart meter.
