Based on the field failure analysis data of the electric energy meter,the black screen faults of the single phase smart meter were analyzed by using the fault tree analysis method in this paper. Firstly,fault statistics and me-ter structure analysis were made,and the causes of black screen of smart meters were grossly classified and analyzed. Secondly,faults reasons were detected individually according to each unit ,and a fault tree model was constructed. Lastly,by means of the fault tree model,a qualitative analysis and quantitative analysis were made ,the minimum cut-set was identified,and the failure rate of the system black screen faults and the probability importance of the mini-mum cut-set were calculated so as to determine the sequence of fault location and analysis,which could provide ad-vice for quick and accurate detection and analysis of the smart meter black screen faults.
