FactorsSresulting inSconditionSmonitoring of low voltage meter are complex and fuzzy. A method in this paperSisSusedSto solveStheSquestion,SwhichSisSbased on AHP-Grey fixed weight clustering for estimating conditionSmonitoring of low voltage meter. First, theSdefinitionsSof low voltage meter’s conditionSmonitoring are provided, theShierarchicalSmodel of low voltage meter is established, theSweightsSofSeachSindex are calculated, then, theSclusterSanalysis is processed by graySclusteringSmethod, and conditionSmonitoring of low voltage meter is ultimately finished. TheSanalyticalSresultsSofSan exampleSshow thatStheSmethod is reliableSandSreasonable.
