First, from the point of view of production and management, the importance for developing TTU is pointed out.the status in quo of technology,The direction of progress,The demand of practical and fundamentality in Distribution Automation are analyzed for Transformer Terminal Unit. The function of equipment and technical specification which meet demand of practical duty are indicated; Second, the scheme of synchronous sampling,quasi-synchronous sampling,non-integer cycle sampling,nonsynchronous sampling and algorithm are analyzed in detail. Then,the scheme of nonsynchronous sampling and multi-chunnel is ascertained. Moreover, the method of disposal sampling data for increasing precision which calculate the number of sampling per cycle dramatic by searching zero is introduced. The technique for analyzing data,stating data,storage data for Electrical Power Quality and control scheme for compensation capacitor are explained also. Finally, The scheme and structure of hardware,key circuitry using 80C196 singlechip,the scheme and ideology of software and flow chart of part software is introduced simply.
