| Abstract: |
| Reliability prediction is an important technique to improve the inherent reliability of smart electrical energy meters and its key is to select the appropriate reliability prediction handbook. The characteristics and limitations of a few prediction handbooks are analyzed and it is pointed out that， according to the inherent characteristics of smart electrical energy meter and its requirement for reliability prediction，Telcordia SR-332 is at present the most practical handbook with great theoretical and engineering values. The reliability of smart electrical energy meter is predicted with the chosen handbook and the predictive results are compared among several kinds of smart electrical energy meter，according to which，some measures for improving the reliability of smart electrical energy meters are given. |
