The Sampling Method and Rotation Strategy of the Smart Meter Based on the Stratified and Staged Sampling Method

Abstract

There is a large cost during the inspection and rotation of the smart meter. In this paper, the 8-year life cycle of the smart meter is divided into 4 stages. Smart meters are sampled through a stratified and staged method, based on the qualified rate and error factors. After the final inspection in the life cycle, the rotation benefit is evaluated by the score of the state of smart meters, economic benefit, management benefit and social benefit. And the problem whether it is needed to rotate the smart meter or not can be solved based on the value of the rotation benefit.
