Abstract: How to accurately analyze and assess reliability and life of smart meters under the multi-stress and multi-parameter condition is a very hot research topic currently. Firstly, the performance of smart meter under conditions of temperature, humidity, electrical stress, vibration and magnetic field were analyzed, and the key performance parameters and sensitive stress were extracted based on failure mechanism analysis. Secondly, the limiting conditions of key performance parameters were explored through enhancement experiment. Finally, an acceleration lifetime experiment program according to the result of enhancement experiment was designed to obtain the key performance degradation data with integrated testing system and establish the degradation trace model, analyze the multi-stress acceleration model, and eventually comprehensively evaluate the smart meter reliability and life. The proposed methodology of evaluating smart meter reliability and life with enhancement experiment and acceleration experiment, the research thought and conclusions can provide theoretical support for the improvement of smart meter reliability and life.

Key words: smart meter, multi-stress, multi-parameter, enhancement test, acceleration life test
