【Abstract】 A correct method for measuring the fundament component of power in a high distorted three phases system is described,Its cost is rather low.The measuring cirtuit mainly consists of two pieces of 8 digit ADC and a piece of RAM.The data are sent to PC through interface after being sampled and the measuring accuracy is improved by using window function、digital filtering and other sofeware processing.更多还原
