Abstract As the main device for collecting electricity, the high reliability and long life of smart meter are particularly important.Reliability prediction is an effective means to quantitatively evaluate the reliability of smart meters and also provides a reference for the design improvement of smart meters.The key to carry out the prediction is the selection of reliability standard. The principle, process, advantages and disadvantages of the commonly used prediction standard are introduced.Three standards were selected to predict the reliability of a single-phase fee-controlled watt-hour meter. Through comprehensive analysis and comparison, the failure rate of GJB/Z299C was nearly twice higher than that of other standards.
