An accurate assessment has an important significance to the stable operation of power system as well as the accuracy of power measurement.An electronic power meter prediction software which uses Telcordia SR-332 is designed and developed on VC in this paper.The software consists of three modules which are users interface module,reliability calculation module and databases operations module.With the input of a power meter model,the software can rapidly calculate the failure rate on device level,unit level and system level as well as the reliable life span of the system. The operation of the software is simple and convenient,it can greatly shorten the time for power meter reliability prediction and the result given by the software is accordance with statistical data.
