0.2S 3-PHASE MULTI-FUNCTION ENERGY METER SOLUTION BASED ON A BLACKFIN PROCESSOR

摘要

Designing a high end 3-phase multifunction energy meter is a difficult task. Often, selecting a good solution is the most important step for design engineers. The requirements for a 3-phase multi-function power meter are always changing, as these meters are incorporating more advanced features and more new functions each year. New 3-phase multi-function energy meters can calculate active and reactive energy in four quadrants, as well as the base wave and harmonic wave energy. These meters can also perform harmonic analysis and intelligent data reading functions. Active energy measurement requires a class 0.2S energy meter, while typically, class 0.5S is required for reactive energy. Any new 3-phase multi-function power meter must be able to support the different protocols and requirements specific to different regions of the world.
