The paper introduces the present situation and problems in reliability evaluation research of electrical me-ters, and proposes that the reliability prediction and reliability accelerating testing are two important technologies for reliability assessment of electrical meters, of which the realization methods, peculiarity and limitation are discussed. Based on the technical features of meters and the requirements of reliability evaluation technology, the reliability pre-diction based on component stress method and reliability test combining accelerated life testing with accelerated degra-dation testing are proposed, which are the most valuable methods applied in reliability evaluation of electrical meters in theoretical and practical engineering.
