With the development of the society, the demand of electric power becomes bigger and bigger. The phenomenon of unbalanced electricity in different time is worse and worse. In order to adjust electric power burthen with reason and save energy, we put forward the design of a novel multi-rate three-phase watt-hour meter. The design principle of a newfashioned multi-rate three-phase watt-hour meter based on PIC16F946 is proposed in this paper. The designs of hardware and software flow, as well as the analysis of experiment data are presented in detail. By trial manufacturing in Zibo Billion Electron Limited Company, it demonstrates that this multi-rate three-phase watt-hour meter has the characteristics which are walking precision, automatic meter reading, accurate measurement, flexible time period setting and low cost. Therefore, this novel multi-rate watt-hour meter has a broad application prospect.
