Impacts of Intelligent Watt-Hour Meter Battery Undervoltage Frequently Power Lost on Metering Performance and Processing

Introduction was made to the measurement function disorder and economic loss in the process of frequently power lost when the intelligent watt-hour meter in the actual operation, affected by itself and the quality of power supply voltage quality. With specific experiment as an example, this paper analyzed the reasons of measurement function disorder due to improper hardware selection and software design defects. Starting from the watt-hour meter related technology and selection of design, this paper analyzed the reasons and gave the optimization and solu-tion, to solve the problem that frequent watt-hour meter off has impact on the electric measurement of power grids at the time of battery under-voltage.
