Abstract
1980s, move towards the market gradually along with the electric power, used electricity the marketing to propose to the electrical energy measurement work a higher request, the electrical energy measurement instrument had to undertake the function more and more were also many, like in the electrical power system, was more effective for the guidance user, reasonably, uses the electrical energy balanced, avoided the peak load the appearance, enhanced system the load factor, achieved the electrical network economy movement the goal, needed to implement the time sharing measurement to the user; Also like, for carries on the online monitor to the electrical energy measurement installment, the distant place remote control, needs to carry on the distant place correspondence to the electrical energy table and so on.At the same time, along with society's development, the transaction electric quantity is more and more big, for, also more and more cared about with both sides to own rights and interests, this set the more and more high request to the electrical energy measurement instrument accuracy rank.
This graduation project carries on the design through the microelectronic technology and the monolithic integrated circuit application technology to the three-phase four duplicate tariff gauge table.
Keywords: The electrical energy measurement, wireless copies the table, the correspondence, the duplicate tariff
