Abstract A microprocessor-based device to measure active and reactive power in a three-phase system is described in this paper. The algorithm is based on the Fourier series technique. The design of the hardware and software, and construction of the device are described. Two microprocessors and a digital hardware multiplier have been used to meet the computational time requirements of real-time operation. A comparison of the results of static and dynamic tests on this device and an analog measuring device show that the digital device is fast, stable and accurate.
