The invention relates to a fault phenomenon correlation analysis method for removed electric energy meters. The method comprises the following steps: 1) distinguishing electric energy meters accordingto fault types and fault quantities of the removed electric energy meters, and dividing the electric energy meters into a single fault type and a composite fault type; (2) eliminating electric energymeter faults caused by user or worker installation problems by virtue of troubleshooting; (3) dividing the troubleshot electric energy meters into different units according to different batches, andrespectively calculating a fault occurrence correlation coefficient for the electric energy meters in each unit; and (4) further analyzing fault occurrence time of electric energy meters correspondingto correlation faults with respect to correlation faults with the correlation coefficient exceeding 0.4, and judging whether correlation fault belongs to the electric energy meter correlation fault in the batch. According to the analysis method disclosed by the invention, the correlation of the electric energy meter faults can be accurately and reasonably evaluated, so that the reliability of electric energy meter assets is improved, and reasonable correlation pre-estimation is made for electric energy meter correlation fault disposal.
