This dissertation discusses a metering concept design that is based on equipment cheaper and smaller than a laptop which is able to meet the requirements of power measurements, such as those for non-active power, that need relatively high frequency, simultaneous sampling. An Analog Devices ADE7878 energy measurement IC is used for measurement of a three phase system instantaneous voltage and current. A STMicroelectronics STM32F4 ARM Cortex M4 is used for the digital signal processing. The software uses direct memory access and high speed data capture to allow enough time to perform the new general power theory proposed by Gaunt and Malengret . The results are tested to ensure there is no data corruption and basic calibration is performed. The system has an upper limit of 2 000 Hz sampling frequency at which power calculations and instantaneous, simultaneously sampled voltage and current values can be output in binary format to an SD card without loss or corruption of data. This project considers only the ability of the system to accurately perform the power calculations.
