Electric energy meter condition assessment based on fuzzy analytic hierarchy process

The operation error of the electric energy metering device directly affects the accuracy of the electricity trade calculation, so it's very important to ensure the device working accurately. In this paper, three levels of indexes of electric energy meter were selected from the life cycle management, which cover basic information, operational monitoring and site inspection. Then the state evaluation system of electric energy meter was established. By variable weights, fuzzy analytic hierarchy process (AHP), we have established a state energy meter integrated assessment models. Using this model, the electric energy meter's condition assessment result can be obtained by every index's condition, which can provide the basis for adjusting the period of test and replacement for electric energy meter.
