Research on failure mechanisms of domestic intelligent electric energy meters

Abstract

Based on the repair records of malfunctioning electric energy meters in each province in China and using repair diagnoses, this article classifies failures by functional modules and analyzes failures under each type of malfunction. The focus is on the mode of failure and mechanism of the components and parts and on finding out the environmental stress that caused the failure, suggesting corresponding improvement measures for each link in the design and manufacturing of electric energy meters.
