In order to achieve energy saving and high efficient use of energy, which is needed for power parameters for accurate, real-time monitoring; in addition, the electric parameters with high accuracy, multi parameter measurement, and fully understand the operation of power system, find and solve emerging in power system the important way of the problem.Therefore, for the measurement of electric power parameters, especially high accuracy, multi parameter, low price, portable, stable and real-time measurement is particularly important, people has always been an important direction in the study. In order to solve the problem above, this design uses ARM7 nuclear LPC2124 chip measurement system for the core, mainly for the power system of our country distribution of the actual situation, through the ARM7 single-chip microcomputer as the core, with a
