Design and Application of Three-Phase Reactive Power Current Digital Measurement and Transmission

This paper introduces one method of digital reactive power current measurement, researches on the principle of measure circuit. Software and hardware principle of the long-distance measurement network that use the method of three-phase reactive power current digital measurement is given in detail. The measurement error and the measure of improving precision are also analyzed. The measure terminal has a microprocessor kernel and high precision circuit, behaves simply and reliably. Current RBUS are used in the network, so it is convenient for computer control and management.
