Application of Fault Tree Analysis on Smart Meter Fault Diagnosis

Abstract

It is of great significance to study and analyze the fault causes and rules of smart meter, quickly and accurately judge the fault location of smart meters, and improve the reliability of smart meter. Based on the analysis of smart meter's structure, the fault tree of smart meter is established. The quantitative and qualitative analysis methods of fault tree are used to sort out the characteristics and rules of smart meter's fault, and the weak links and key parts of smart meter are determined. The application results show that the fault tree analysis can effectively help technicians to locate faults quickly and reduce the processing time of faults, which has a good practical value.
