Abstract:With the increasing complexity of electronic equipment, the reliability of electronic equipment is becoming more and more prominent.Because the factors that affect the non-operation of electronic energy meter are more and more complex than the inductive power meter, the reliability of the electronic energy meter is higher.This paper analyzes the electronic watt-hour meter reliability evaluation technology development present situation and existing problems, combined with the technical characteristics of watt-hour meter and reliability assessment of technical requirements, proposed the accelerated life test and the component stress method two kinds of forecasting method, the two methods is the most practical reliability prediction of electronic watt-hour meter, most theoretical value and engineering application value of technical methods and is helpful for the electric power enterprise to choose higher reliability, long service life of electronic watt-hour meter, electric power system operation cost is greatly reduced.
