Failure Mechanism and Effect Analysis of Metering Module of Smart Meter

摘要

The Failure Mode, Mechanism and Effect Analysis (FMMEA) method is a reliability analysis method that investigates the possible failure mechanisms and their failure modes for each component of the product, then determines how each failure mechanism affects the other components. This article uses the FMMEA method to analyze the failure mechanism of the smart meter's metering module. Based on the analysis of actual environmental conditions, the main failure mechanisms and the corresponding sensitive stresses of the metering module are determined, which provide the basis for the smart meter's reliability index verification test design.
