| Abstract: | Based on theoretical analysis,the paper discusses the key parts of the electric power andenergy meters-multipliers deeply,and compensation for their errors with microcomputers.Italso deals with the selfcorrection of the meters using the method of substitution.Experimentshows that the principle of the measurement system can be brought into practice and itaccords with the demands of the 0.05 grade electric power and energy meters. |
