摘要：

Reliability assessment test for smart electrical energy meters is specially designed based on the failure mechanism of the components used in the product. Firstly, malfunction data of the meters in the field is collected and classified. Failure analysis is carried out to find the ultimate causes of the failure. Failure mechanism is then clarified and possible stresses of suitable strength levels are designed to stimulate the weaknesses or accelerate the aging process. Through some well-chosen tests, latent weaknesses of the products are exposed. The results of this reliability assessment test for smart electrical energy meters are effective and accordant with the field failures. This reliability assessment test is thus proved valid in evaluating the smart meters in practice.
